Led Zeppelin - Dazed and confused

Jake Holmes wrote Dazed and Confused for his debut album "The Above Ground Sound" of Jake Holmes, which was released in June 1967. In August 1967 Holmes was the opening act for the English rock band The Yardbirds. They heard and adopted the song and added drums and a guitar solo. By the time The Yardbirds became Led Zeppelin (first The New Yardbirds), Jimmy Page had already credited the song to himself.
