In the 70's Barry Manilow was hugely popular and even starred in a Dr. Pepper commercial. The commercial is circa 1976 and featured Barry singing a song about Dr. Pepper. This commercial seems to be rare for Barry Manilow fans and considering how popular he was in the 70's this commercial is fun to see
