Good stock early UK disco tracks include "Blue eyed soul", "Summer of '42" and "You don't stand a chance..." from Blue-Eyed Soul; "Chic-chica-chic-chica-chic" and "Laura" from Rain Forest; "Funky tropical" and "Boogiethon" from Eastern Man (both excellent); and the silly "James Bond disco theme" from Futuristic Journey.
The US-only 12" of "Rainforest" was one of the first ever 12" on the Epic label. "The Stud" is the discofied theme to the Joan Collins movie of the same name, and is available on Canadian-only 12".
