The Grateful Dead’s Rex Foundation is teaming up with the Jake Peavy Foundation to offer music and baseball fans a chance to meet both Peavy and Dead drummer Mickey Hart at the San Francisco Giants’ final regular season game.

Through donations, fans are entered to win a VIP package to the game that includes a flight to San Francisco, a stay in a four-star hotel, premium tickets, dugout access and a post-game meet and greet with Hart and Peavy, where the two will get together for a musical jam.

Interested fans can enter here and find out more about the various prizes available for donations, including signed memorabilia.
