In the early 1960s, Kircher toured Germany doing club gigs as the drummer for The Burnettes, a band featuring Neil Landon as singer and Noel Redding playing guitar.

More session work followed, before Kircher was recruited in April 1967 to join Honeybus, who although often written off as a one-hit wonder with their track “I Can’t Let Maggie Go” in 1968, produced a sizeable body of baroque pop music which culminated in a critically acclaimed 1970 album, Story, which was released after the eventual dissolution of the band.

His time in this band took him up to 1981, taking in a session playing drums on the Nolan Sisters single "Who's Gonna Rock You", before being invited to join Status Quo following the resignation of John Coghlan.

This, in turn, directly led to Kircher's induction into a group of session musicians for John Du Cann's The World's Not Big Enough album in 1977, which was produced by Quo's guitarist Francis Rossi.

As well as drums, Kircher contributed backing vocals to the bands he played with, and test pressings of a 1973 solo single – "Rockin' Lady" – are known to exist.
