To back Gareth's account up, I remember when Ian Clark made this available to the "masses" by finding an unknown quantity. He first sold them through the small ads of Black Echoes in April 1983 at £7 each. I phoned Ian to ask him if they were original, and he told me they were as he'd just found a load of them in the States. My copy arrived a week later, and it was the green/white issue with slapdash credits (jan jones rather than "Jan Jones"!!).
As far as I remember, Keb dropped it from his playlist in February that year, along with all other 70s/80s newies he previously played (eg, Cheryl Berdell, Curtis etc), to make way for the big "60s Mafia" sounds soon to take Stafford by storm, but that's another story!!
