Bryan Adams, Maroon 5, Train and Barry Manilow are among the artists giving out Vip concert tickets as part of a charity auction.
Each of the acts is offering up two gig tickets to raise money for the 15 Foundation's It's For the Kids auction, which will benefit children's nutrition education programs in California.
Actor John Stamos and Robin Williams have donated autographed scripts to the fundraiser, while comedienne Sarah Silverman has offered to record a voicemail message for one lucky fan.
The 15 Foundation fundraiser is running on the Charity Buzz website until 18 May (11).
