Not my cuppa - but for those interested there's a track by Richard Torrance on his Capitol LP "Double take" called "Runaround Girl"
I guess this is the mystery track?
I'm sure you want comments on the tracks rather than a track list. But as I don't have it, I'll start things off with this taken from Popsike:
From 1971, out of New Jersey, comes Gloria Barnes with her LP Uptown on Maple M6006. Ultra rare ORIGINAL PRESS of this extremely rare soul/funk LP! Contains the song I'll Call You Back Later, parts of which have been sampled on various records. Eight songs on this LP, including Old Before My Time, I'll Call You Back Later, I Found Myself, Gotta Get Away, You Don't Mean It, Home, She Wants A Stand-In, and I'll Go All The Way. This ultra rare LP features Lee Moses and The Deciples on several of the songs as back-up. The Ohio Players may have been involved in several other songs.
John Benson's post in Jimmy Scott - You're A Runaround was marked as the answer
