But did you previously know it wasn’t the Belmonts backing Dion up on so many of the big hits credited to Dion & the Belmonts? I believe it may have the choice of the group that actually did the backup on those songs, ie, the Del-Satins —later to join Johnny Maestro in Johnny Maestro and the Brooklyn Bridge.
Songs performed with the Del-Satins doing the backup (as opposed to the Belmonts) include: “Runaround Sue”, “The Wanderer”, “Lovers Who Wander”, “Little Diane”, “Love Came to Me”, “Ruby Baby”, “Donna the Prima Donna” and “Drip Drop”.
Those songs are from the 1960's. By the way, I read that the Del Satins were named after two popular rock groups at the time, the Dells and the Five Satins. They waxed a few discs without Dion, including Feeling No Pain (1963), a song Jim Pewter liked to play on his "oldies" show broadcast over the Armed Forces Network.
By the way, I like the Drifters' version of Ruby Baby (1956) and Drip Drop, two fine products from Ahmet Ertegun's Atlantic label.
