The Marvelows were an American soul group from Chicago. After contacting Johnny Pate, the group signed with ABC Records and recorded four sides: "A Friend", "My Heart", "Hey Hey Baby", and "I Do". The last of the four was released as a single and became a U.S. hit, peaking at #7 on the Black Singles chart and reaching the Top 40 in the Billboard Hot 100 at #37. It was later covered by The J. Geils Band, in 1982.

The group changed its name to The Mighty Marvelows in order to avoid being confused with The Marvellos, and hit the charts only once more, with 1968's "In the Morning" (U.S. R&B #24). A 1968 LP followed, entitled The Mighty Marvelows, but the group broke up in 1969, reuniting only once, briefly, in 1974.
