(Untitled) is the ninth album by the American rock band the Byrds and was released in September 1970 on Columbia Records. It is a double album, with the first LP featuring live concert recordings from early 1970, and a second disc consisting of new studio recordings. The album represented the first official release of any live recordings by the band, as well as the first appearance on a Byrds' record of new recruit Skip Battin, who had replaced the band's previous bass player, John York, in late 1969.

"Mr. Spaceman" is a song by the American rock band the Byrds and was the third track on their 1966 album, Fifth Dimension. It was released as the third single from the album in September 1966, reaching number 36 on the Billboard Hot 100, but failing to chart in the United Kingdom. Upon its release as a single, the music press coined the term "space-rock" to describe it, although since then, this term has come to refer to a genre of rock music originating from 1970s progressive and psychedelic music.
