Jon Hyde was the singer for the early 1970s group Hokus Pokus, who had one album on Romar Records in the early 1970s, featuring former Stooges keyboard player Scott Thurston, former Yellow Payges drummer Danny Gorman and former Steppenwolf guitarist Michael Monarch. They played the Hollywood clubs quite a bit at that time, and were regular patrons of Rodney Bingenheimer's club on Sunset. Jon and Michael Monarch later formed Detective with Michael Des Barres from Silverhead and signed with Led Zeppelin's Swan Song Records. Jon was the drummer for Detective but wrote most of the lyrics and material, as he was a lead singer himself. He did the drumming on the Hokus Pokus album as well.
