"Movin' On" is a song written and recorded by American country music singer Merle Haggard and The Strangers. It was released in May 1975 as the third single and partial title track from the album Keep Movin' On. Originally, it was the theme song to the 1974-1976 NBC-TV series of the same name and references the lead characters of the series, Sonny Pruitt and Will Chandler, by name. A full-length version of the song was released as a single in 1975, and it topped the Billboard Hot Country Singles chart that July.
