The Box Tops were an American rock band, formed in Memphis in 1963. They are best known for the hits "The Letter", "Cry Like a Baby", and "Soul Deep" and are considered a major blue-eyed soul group of the period. They performed a mixture of current soul music songs by artists such as James & Bobby Purify and Clifford Curry, pop tunes such as "A Whiter Shade of Pale" by Keith Reid, Gary Brooker and Matthew Fisher of Procol Harum, and songs written by their producers, Dan Penn, Spooner Oldham, and Chips Moman. Vocalist Alex Chilton went on to front the power pop band Big Star and to launch a career as a solo artist, during which he occasionally performed songs he had sung with the Box Tops.
