Wavy Gravy has been the recipient of numerous notable birthday bashes over the years. Last year Phil & Friends performed at a SEVA Benefit in his honor at the Berkeley Community Theater. In 2001, to mark his 65th birthday, Mickey Hart, Jorma Kaukonen and Jack Cassidy, Dr. John, Indigenous, Paul Kantner, Pete Sears, Maria Muldaur, Diana Mangano, and Box Set were on hand. In 2006, to celebrate his 70th, the SEVA Foundation will once again receive proceeds from a night of music that will feature RatDog, Mickey Hart and Friends, Steve Earle, Gillian Welch, David Lindley, John Trudell, Hamza el Din and the birthday boy himself. The event will take place on Saturday, May 20 at the Berkeley Community Theatre, with some special receptions also available to those who make donations in support of SEVA.
