Inspired by “You Need Love” by Muddy Waters (1963)
and “You Need Loving” by Small Faces (1966).
Hit version by Led Zeppelin (US #4 1969).
From the wiki: “In 1962, Muddy Waters recorded ‘You Need Love’, written for him by peer Willie Dixon. In 1966 British mod band the Small Faces recorded the song as ‘You Need Loving’ for their 1966 debut album. Some of the lyrics of Led Zeppelin’s version were copied from the Willie Dixon song, a favorite of Plant’s. Plant’s phrasing is particularly similar to that of Steve Marriott’s in the Small Faces’ version. Similarities with ‘You Need Love’ would lead to a lawsuit against Led Zeppelin in 1985, settled out of court in favor of Dixon.
