"You're Not The Only Girl" by Jigsaw

The British pop band Jigsaw scored one major hit in the US when "Sky High" flew to #3 in 1975. You can comb through their entire catalogue, but I don't think you'll find a better song. I should know because I tried. "You're Not The Only Girl" is the best I could find as a close second. I like it even more than the band's only other top 40 hit, "Love Fire," which reached #30 in 1976.
