Can you identify this old song. I think it is a barbershop quartet or do-wop style mostly remember guys in the background repeating dum dum. from 60s. Any Ideas?

The song that you are referring to is "Sh'Boom" by The Chords. It was released in 1954 and was a huge success, reaching number one on the Billboard charts. It is a classic example of the do-wop style of music and is still popular to this day.
