Can anyone name this do op song?

I don't know so much about it...I heard it on the radio this morning and it was my a group balled Bell Munch Trio or something like it? The group had a couple words in it's title and one of them definitely started with a B. I also think it's probably a pretty popular song because it was on a greatest hits station. It was very up beat and do op-y, lots of harmonizing. Very fun!
