why did you give a clue "not bue but ...green" that's just leading people astray if the greenbeats were gone.  have you any way to prove that you're right?  I really can't see John Keogh doing that.  One  recording  Full circle did in the late 70s was an excellent R&R album called "Party Hits" or similar.

Kim Newport's single "Stop Think" was written by John Keogh, and he produced "The Live Mike" TV series which provided him with a platform for his many gags and antics. He also produced Larry Gogan on radio and if Larry wasn't such a gentleman he'd have a few tales to tell!
But Heffos Heros?  prove it.

Whistle will ya get a life .If the man says its John Keogh just believe him.He would not be the first to release a record under another name sure didnt Horslips do it at the height of their fame and so did The Saw Doctors.

I really dont know why i bother but i have been on to a collector friend of mine in the hope of putting this to bed.According to him he remembers it was someone from the 60s who was behind it and he checked the single for me and here are the details writers as follows .
J Koff / S Frank also wrote the b side .

Those names look a bit iffy to me so it certainly could be  the man himself.
