The Green Brigade have announced they've raised over £12,000 for their Scottish Cup Final tifo in memory of Billy McNeill and Stevie Chalmers.
And the ultras group will donate £1,967 to Alzheimer Scotland, after both Lisbon Lions passed away last month following battles with dementia.
The Parkhead side have been mourning the 1967 European Cup heroes and both the club and the Green Brigade are planning a day to remember.
Celtic will wear numbers 5 and 9 on their shorts for the Scottish Cup Final in memory of the legendary duo.
The players will also walk out wearing alternate jackets with McNeill 5 and Chalmers 9 emblazoned on the back.
And the fans group have announced detailed plans for all supporters to follow before kick-off.

The statement read: "As you will know, the Green Brigade have been fundraising to mark the 2019 Scottish Cup Final as we hope to produce something fitting of this historic occasion.
"Naturally, there will be another occasion on our minds on the 25th of May. As our current team bid to cement their own legacy, the Lisbon Lions will be cause of inspiration and none more so than the late Billy McNeill and Stevie Chalmers.
"With the two Celtic legends in mind, we ask the entire Celtic support to participate in a tifo which will honour both, creating a fixed wall of colour to drive our team on every step of the way to history.
"We ask that every fan wears the bib found at your seat from the moment you arrive and for the duration of the game; and stress the importance of full participation in order to achieve the desired effect.
"In addition to this, fans in the East Stand (traditional Celtic end) will find a second piece of material at your seat. As with most other tifos, we ask that you use this as the team emerges from the tunnel. Again, success relies on full participation – especially important here as there will already be a tifo beneath which the ‘2nd tifo’ should mask.
"As always, the Celtic support have rallied round our appeal and we thank you for your generosity. Between paypal donations and Sunday's bucket collection, an impressive £12,052.78 has been raised to support the costs of the tifos. As promised, £1,967 will go to Alzheimer Scotland in memory of Billy and Stevie.
"On Saturday, we trust that the support will prove once again what sets us apart from the rest, as we produce a show of colour and noise both fitting of past heroes and deserving of current ones."
