Ask yourself honestly, when was the last time you'd seen Goodison Park like it was on Thursday evening?
It was even made better by the fact there was a little trepidation in the air pre-match, a feeling this could be one of the biggest matches in the club's recent history. The explosion of emotion when Alex Iwobi rolled that ball into the back of the net was awe-inspiring, breath-taking - something which no other ground in the country can really replicate.
If you haven't watched the "goal from every angle" video that Everton put on their YouTube channel yet, then take the time to do so. You absolutely won't regret it.
One view focusing on the Park End, right behind where the goal was scored, summed up the raw energy on display. A steward was dancing in front of one of the exits, someone was waving their crutches in the air with delight.
These feelings are what Goodison Park used to be all about, but has been allowed to really achieve in recent times. There's always been something holding it back.

Carlo Ancelotti was essentially robbed of that emotion during his time at the club, with the coronavirus pandemic forcing his side behind-closed-doors for the majority of his spell. Rafael Benitez was always fighting an uphill battle to try and create anything like those scenes at full time yesterday.
Granted the latter achieved some big moments this season most notably against Southampton, Burnley and Arsenal - but he wasn't able to truly harness that power on a consistent basis. Evertonians could buy into the players and their actions, but they couldn't relate to the manager.
And so, amid all the wild dancing and jubilation, perhaps it was Frank Lampard's celebration - and that of his backroom staff - which was the most important to note. A celebration, of course, which left him with a broken hand.
He's clearly not bothered by the injury, despite it looking swollen and painful in Friday's press conference at Finch Farm, with two of his fingers taped together. In fact, in a strange way, it could be seen as a badge of honour.
Now the real work starts for the manager, however. The pressure is on for him to make sure that this is not a one-off, and he doesn't fall into the trap that the man before him did.
Of course, much of that is going to be down to the players and whether or not they can take up what Lampard is dishing out. After all, they're the ones who need to perform during a 90 minutes - and have not been doing that consistently enough throughout the course of 2021/22 thus far.
But the current Everton boss has realised from the beginning that a connection with the fans is the first step to him improving what is happening at the club. And, it's the best way for him to get the time he really needs to succeed.
The Blues have gone down the route of a younger, less experienced manager and he knows he hasn't got a "magic wand" - as is the phrase he's used a lot since his appointment in late January. Patience might be at a premium in modern football, not least with Everton's current struggles, but everyone knows they need a period of stability.
Buying into what Evertonians want to see from their team is part of the process, but actually feeling the raw emotion and passion along with them is crucial as well. That bleeds into the players, and it showed in their reactions to Iwobi's late strike on Thursday night too.
But, it's not the be-all-and-end-all. There's been time to sit back and take in the context of the match and, while the emotion of the day was fantastic, circumstances dictate that it won't be the same in every match.
For a start, Everton won't be able to feed on that passion from the fans in their away matches throughout the rest of the season, which are just as important as the home games. In fact, for many of those clashes, they'll be on the wrong end of a big atmosphere.
Time and again over the course of this campaign so far, the Blues have shied away from that responsibility. They have retreated into their shells rather than taken pride, confidence and momentum from the rousing home victories they managed to secure.
Lampard said in the build up to this weekend's match against Crystal Palace: "It will be the flip, Palace have got really strong support. Really loud, very vocal and they're in a similar position to us - a team desperate to get to Wembley and try and win something this season. It will be a test of character in a different sense.
"I like the character of the team, I know that people are questioning it at the minute and think it's time for them to stand up and show that, they certainly did last night (Thursday) and must in a different way on Sunday. The test will be standing up emotionally and showing your character, but also on a football level we need to be better away from home."
It might have been a long time since you've seen Goodison Park like it was on Thursday night, and that can certainly be a big motivator for the squad. But, at the same time, it also may bring with it a warning.
You can't rely on the fans every week, and Lampard knows that. He has bought into what the supporters desire, and he's feeling the same as they do.
That should afford him the time he needs to have a real crack at this job. Keeping the club in the Premier League and assessing across what will be a very interesting summer is the prime concern.
But, of course, an FA Cup run wouldn't go amiss. So, Everton will need to turn a huge atmosphere at Selhurst Park on its head.
That's the real test now.
