This one was written by a certain Gene McDaniels (a.k.a. Eugene McDaniels), a singer-songwriter for Atlantic records, and a groovy solo artist in his own right. This song also has a connection with soul-jazz keyboardist Les McCann. McCann saw Roberta Flack perform at a benefit concert (back when she was a schoolteacher), and was so impressed he had her guest on his album "Les Is More" in 1967 as one of her earliest recorded appearances. An early studio version of "Compared To What" was on this album (although she does not sing on the song).
