The great Glee cast donated two pieces of autographed sheet music to Clothes off Our Back, an organization that raises money to benefit children’s charities by auctioning off items donated by celebrities.

Both pieces are autographed by every single member in the ensemble. The sheet music for “Somebody to Love” is currently $700 and the cast lyrics for “Somebody to Love” are currently $350. The bidding ends at 9pm EST tonight, so you better hurry!
