Did you quote the wrong post here Robb? Some valuable information but I don't see what the connection is between Harry Balk and The Appreciations. The relevant bit from the article:
"Their next recording was “I Can’t Hide It” / “No, No, No” (Aware 1066). Hattie set up Aware for this sole release. The tracks were recorded in 1966 at the Golden World / Ric Tic Records Studios in Detroit. The group liked the Motown sound and wanted to be part of it. Willie Mitchell (band leader, producer, wind and keyboard player) coached and arranged the session and, according to Charles, played baritone sax. Mitchell is perhaps more associated with Memphis than Detroit. In reality however he wrote, produced, arranged and recorded a number of tracks for Lee Rogers, Buddy Lamp and others on Detroit labels such as Wheelsville, Premium Stuff and D-Town, either from his Memphis base or in Detroit itself. The Aware release enjoyed some success in the south east and mid-west regions."
Seems like a perfect example of the phenomenon that the original poster was looking for with a Charlotte based group on a Charlotte Label travelling up to Detroit to use their recording studios.
