"Hey, Hey, What Can I Do" is a song by the English rock group Led Zeppelin, released in 1970 as the B-side of "Immigrant Song" outside the United Kingdom. It is Led Zeppelin's only non-album track released during the band's existence. It did however appear on the Atlantic Records UK various artists LP, The New Age of Atlantic, released in 1972. The song was first released on CD in October 1990 on the 4-CD Led Zeppelinbox set collection. In 1992 as a 20th anniversary release, "Immigrant Song"/"Hey, Hey What Can I Do" was released as a "vinyl replica" CD single. In 1993, "Hey, Hey What Can I Do" was included on The Complete Studio Recordings 10-CD boxed set, as one of four bonus tracks on the Coda disc. The song is not included on the individual version of Coda. In 2007 Led Zeppelin released the track online along with the rest of their back catalogue, as a bonus track on Led Zeppelin III. The song was also released as the B-side of the "Stairway to Heaven" 7" 45 RPM picture disc.
The lyrics tell of a man's love for a woman who "won't be true". The first verse is a declaration of his love and his desire to tell her that she is the only one for him. The second verse describes her infidelity and his jealousy and frustration. In the third verse he comes to the conclusion that he must leave her "where the guitars play," a sentiment reinforced by the vamp in which the lead singer, Robert Plant, is backed by the rest of the band repeating the two lines "Hey hey what can I do" and "Oh no what can I say".
