The early 1970s was a period when horn rock bands like Blood, Sweat & Tears and Chicago were popular and spawned bands like the Ides of March, Lighthouse, and Chase. Hamilton, Joe Frank & Reynolds were a Los Angeles trio who incorporated the sound into “Don’t Pull Your Love,” a №4 hit in 1971.

The 1960s was a watershed era for blue-eyed soul, with multiple hits by the Young Rascals, Mitch Ryder and the Righteous Brothers. Add the Box Tops, whose 1967 “The Letter” became a №1 single and would sell four million copies.
