Here is the 45 on the same purple label. The Velvets and the Rainbows were two of the vocal groups that Pilgrim released records by, previously to the G-Clefs. As a note, those groups had been previously issued on Red Robin.
A odd release from around 1962 on the Ditto label. This was the hit "Ka Ding Dong" backed with the original flipside "Darla My Darling." It appears to have only been issued on blue wax. The C-Quins also had a release on the label with black wax. The label was owned by Skippy White. He was more than just a DJ in the Boston area, he is a legend dating back to the 1950's when he was promoting R+B music. He STILL has a record store in the Boston area at Egleston Square.
The follow-up to the G-Clefs smash hit was another up tempo tune called "Cause Your Mine" It was flipped with a ballad "Please Write While I'm Away." Teddy Scott was on lead vocals on side "A", but the record didn't ride nearly as high as their initial effort.
Here is the 45 RPM version. While the G Clefs were at Pilgrim records, Jack Gold was their "Producer" on the their sides. This was released in November of 1956. After two records on Pilgrim, the G-Clefs followed Jack Gold to the Paris label.
