The intimate set will take place the night before the ceremony.
Q Magazine have announced that the multi-platinum selling Scots are to play a special acoustic show at Camden's Jazz Cafe on 20 October.
The band, who are nominated for two Q Awards including the Planet Rock sponsored 'Best Act In The World Today', will be performing an intimate 45 minute set.
Tickets will only be available via ballot through Biff's fan club and on www.QTheMusic.com from midday today (7 October). All net proceeds from the show will go to Yorkhill Children’s Charity in Glasgow.
