Press Review – "Sunday’s (13th) Jeff Beck, Vanilla Fudge, 10 Years After, Edwin Hawkins Singers concert at Singer Bowl resulted in an unexpected jam amongst members of The Jeff Beck Group, Led Zeppelin and Jethro Tull. The music excited Zeppelin drummer John Bonham to the point where he started tearing his clothes off. He was carried offstage by friends before he could get past his underwear."
