Harkins Twins
A spectacular circus act as I recall. Previous correspondence on this subject is correct inasmuch as there was originally only one Harkins (mono version). The miraculous conversion came about during a particularly hectic inbound rush on TMA(SW) one day, summer, mid 80s. Stevie became so excited, he accidentally reproduced himself via binary fission, and became Nice Steve/Nasty Steve aka The Harkins Twins (stereo version). We can only hope and pray, in these days of Dolby Pro Logic Surround Sound, that the process is complete.
I remember Stevie and Jim McC very well, good drinking buddies and v.dangerous to boot, and bloody good controllers.
