From the wiki: “‘The Pusher’ was written by Hoyt Axton (‘Joy to the World‘, ‘Never Been to Spain‘) after one of his friends died of a drug overdose. The song was one of the first to deal with harsh realities of drug use, and condemns ‘the pusher’ as a heartless criminal who is only after your money. It was made popular by the 1969 movie Easy Rider. ‘The Pusher’ was first recorded as a live performance at The Matrix in 1967 by Sparrow (pre-Steppenwolf moniker). But, according to organist Gordy McJohn, the group’s history with the song began in 1966 when singer John Kay and Jerry Edmonton were late for a performance:
Nick and Mars and me started that long version of ‘The Pusher’. John and Jerry’s flight was late one night at the Avalon Ballroom, so we started and then we perfected it at the ‘Arc’ in Sausalito on New Year’s Eve in 1966.
