- What Could Have Been: Pisces Aquarius went through at least two versions, with various songs added and removed before the finished version was assembled just before release. According to the liner notes for the 1995 CD remaster, this was the original track sequence:
- "Special Announcement"
- "She Hangs Out"
- "Salesman" (the extended version with Michael Nesmith's spoken word bit at the end)
- "Cuddly Toy"
- "Words"
- "Don't Call on Me"
- "Goin' Down"
- "The Door Into Summer"
- "Hard to Believe"
- "What Am I Doing Hangin' 'Round?"
- "Daily Nightly"
- "Peter Percival Patterson's Pet Pig Porky"
- "Pleasant Valley Sunday"
- "Star Collector" (an even longer version than the one that was released)
"Love Is Only Sleeping" was originally intended to be a single, with "Daydream Believer" (which was also meant for this album) as its B-Side. When the record's release was delayed, Colgems decided that "Daydream Believer" would make a better A side (which it did; it became the Monkees' last single to hit #1). "Love Is Only Sleeping" wound up on the album, with "Goin' Down" replacing it as the flip of "Daydream Believer".
