Lenny Hart was arrested in San Diego in the summer of 1971, while baptizing people and using the name "Rev. Lenny B. Hart." 
The Grateful Dead song "He's Gone" is based on Lenny Hart's embezzlement of band money and subsequent disappearance. As a result of the fiasco, Mickey Hart left the band in February 1971, not returning to the group on a full-time basis until 1974.
