"'Cause You're Mine" by The Vibrations

The Vibrations had a string of minor hits through the 60s but should be remembered as much as their contemporaries like The Four Tops and The Temptations.

They first hit the charts in 1961 when "The Watusi" landed at #25 and hit again in 1964 when "My Girl Sloopy" reached #26. The latter became a #1 hit for The McCoys a year later as "Hang On Sloopy."

The group managed two additional chart appearances before their career was over: "Misty" peaked at #63 in 1965 and "Love In Them There Hills" stalled at #93 in 1968.

It should be added that these guys originally recorded under the moniker of The Jayhawks, scoring a hit with "Stranded In The Jungle," which reached #18 in 1956. And in 1961, The Vibrations recorded another hit, "Peanut Butter" (#20), but the record label they recorded under called them The Marathons.

It's a complete mystery way something as amazing as "'Cause You're Mine" failed to reach the charts.
