Always Lindsay Honey when he was 'acting' & even when he directed Rock & Roll Ransom in the early 80's it was under this name. He & Linzi are also given credit, as associate or executive producers, under their real names on the films Buttman did in the UK. They got the girls for him & he used their house for a lot of the scenes. As far as I can tell he began using the Steve Perry alias when he directed 'Anal Manor' for Private in 1993 and has used it ever since as his directing alias.
Apparently he was driving Buttman to London airport after he's just filmed 'Bouncing British Babes' and he suggested to Lindsay that he should do similar type Gonzo productions with an English slant. He took his name from the Buttman 'Bend Over' series & the rest, as they say, is history.
