Radical musicians usually found enthusiastic audiences at Yippie-sponsored events and frequently offered to play. YIP-affiliated John Sinclair managed Detroit's proto-punk band the MC5, who played in Lincoln Park during protests at the 1968 Democratic National Convention. In 1970, Pete Seeger played a Vancouver Yippie rally against construction of a highway through Jericho Beach Park. The first-ever concert by the influential and iconic proto-punk band the New York Dolls, was a Yippie benefit to raise funds to pay legal fees for one of Dana Beal's marijuana arrests in the 1970s.
