As the 1960s came to an end, Ike and Tina began performing at rock festivals. In 1969 they performed at the Newport Pop Festival in Northridge and the Gold Rush Festival at Lake Amador. In October, they headlined the Soul Bowl at Tulane University's Sugar Bowl Stadium; a concert to raise money for disadvantaged minority students. In November, Ike and Tina reportedly upstaged the Rolling Stones as the opening act on their 1969 US Tour. Their erotic performance of "I've Been Loving You Too Long", filmed during a concert at Madison Square Garden, is featured in the Rolling Stones' 1970 documentary "Gimme Shelter". Also at Madison Square Garden, Janis Joplin joined the Turners on stage for an impromptu performance of "Land of 1000 Dances." Ike and Tina added rock songs by the Rolling Stones and the Beatles to their repertoire, which was receptive among crowds. Their new label, Minit Records, responded by releasing their rendition of "Come Together" in December 1969.
