Frankie & The Classicals - What Shall I Do? (1967) Mono (special mix). This song captured the attention of Bill Buster of Eric Records when I initially posted a crude stereo mix snippet. It was Tom Diehl (TopShelfOldies) who brought it to my attention that multiple artists utilized the (music) backing track hoping to score a hit. Honey Townsend ((probably fictitious))instrumental, Mala Records) opens this fine Philly regional hit. Kent Records, a division of Ace Records (UK), published it with an instrumental/spoken word intro that (DJ) Jerry Blavat initially told the record company (Calla Records, NY) to drop, since it's difficult to dance to. Other artists, such as The Essex, also attempted to score a hit with the backing track...

-- So, you are very correct about the recording tape being (trunk) hauled around, hoping to score a hit with some singer/group!!

-- Original Cannibal version issued by Varese Sarabande (CA), I just grabbed the intro.
