Franky & The Spindles were problably from the N.J. area. The group was made up by Frankie Kennedy (lead), Robert Kennedy, Charles Graves, Joseph Shields and Raymond Shields. They are not the same Spindles that recorded for ABC records, that incarnation was problably from the Florida area.
Franky & The Spindles released four singles on Philadelphia based Roc-Ker records between 1968 - 1970, and went on to record for a number of local labels after that as well. Their last 45 came out on the tiny Strawberyy label in 1977.
The Roc-Ker label was co-owned by George Kerr, a well established player in the Philadelphia music industry (he is the "Ker" in the label) and another person who is a this point unknown to me. The label worked as a subsidary to the larger Phil LA of Soul and used various distribution networks to get the product out, in this case the Amy - Mala - Bell setup.
