A recording engineer has commented on discogs that "I lost you girl" was recorded August 15, 1970 at Pioneer Recording in Detroit.
The G&G scan has 19,8,83 handwritten on the label so a 1983 release is not impossible.
(There's also a youtube comment that claims that Perfecta was "named after a racetrack windfall he enjoyed that week". Youtube vid is from his Love Bandit compilation on Norton so maybe info from there?)
Larsc's post in Gino's 'I lost you girl' on Perfecta and on G&G was marked as the answer
