Johnny O’Keefe - You’ll Never Cherish A Love So True (Until You Lose It) (1963)

The Vells - You’ll Never Cherish A Love So True (Till You Lose It) (1962)

(Berry Gordy Jr)
 USA
Original version

Single on Berry Gordy Jr's Mel-O-Dy label, a Motown subsidiary.

Some sources spell the group name as Vels but Vells is on the label.

The Vells had released a single on Chess subsidiary
Checkmate as The Del-Phis, a name they could not use here because they were still signed to Chess.

The group would soon become better known as Martha & The Vandellas, although The Vandellas did not include Gloria Williams, the lead singer on You'll Never Cherish A Love So True: she left the group when the record didn't take off.

Before their first big hit, Heatwave (1963. #4 USA), The Vandellas backed Marvin Gaye on Stubborn Kind Of Fellow (1962).
