"Bobby's Girl" is a song and single written by Gary Klein and Henry Hoffman. The original was performed by American teenage singer Marcie Blane, and became a No. 3 hit on the US charts. A version by British singer Susan Maughan was released in the UK less than a month later, coincidentally also reaching No. 3 on the UK charts. Both Blane and Maughan are one-hit wonders; for both these artists, "Bobby's Girl" marked their only appearance on a national top 40 chart.
