Music to Watch Girls By is Bob Crewe's first top 40 hit with his group The Bob Crew Generation. He had heard the melody (composed by Sidney Ramin) in an advertisement for Pepsi Light. In the original instrumental version, the trumpet and saxophone have a leading role. Andy Williams later turned this into a vocal song. This song is a nice ending to your concert where you let the audience go home singing with a nice earworm of a melody.
