There's a very interesting song from The Byrd's preflyte sessions called You Movin', the song never made it onto Mr. Tambourine Man album unlike some of the other preflyte songs, though The Byrd's made alternative versions of it, alternative version 3 is the one I like because of the songs intro, unlike the other versions which seem to start off with the You Movin' lyric, because of the songs intro the song properly starts with a verse, though perhaps the band said instead of singing the 1st bit, we'll play it out instrumentally.
Here's alternative version 2 by comparison
