One of the first San Francisco psychedelic bands, the Mojo Men began as a British Invasion inspired group, even covering the Rolling Stones' "Off The Hook". But following the arrival of drummer Jan Ashton, the group developed more intricate arrangements and harmonies that reflected the psychedelic folk/rock influences of bands like Jefferson Airplane and the Mamas and the Papas. They were one of the premier bands that help shape the San Francisco Sound.
Their only Top 40 hit was their cover version of a Stephen Stills' song he wrote and sang for Buffalo Springfield. It was entitled "Sit Down, I Think I Love You", released in March 1967, and featured a new member, Jan Ericco/Ashton, a female vocalist/drummer who had defected from another San Francisco band, The Vejtables. According to The Book of Top 40 Hits by Joel Whitburn, "Sit Down, I Think I Love You" was on the Top 40 for three weeks and peaked at number 36. Whitburn failed to include Jan Ericco's name with the other members.
