Uncredited Byrds track?

I hadn’t listened to the “Candy” soundtrack LP for years.

I did a couple of days ago, and when listening to “Ascension To Virginity” by Dave Grusin, I couldn’t help thinking I was hearing The Byrds.

Some research led me to someone who plays on the album; he said it was Dave Grusin on keyboards, Gene Parsons on drums, Clarence White on guitar and probably John York on bass. He couldn’t remember about McGuinn being there as well.

Seems like an uncredited Byrds track to me.

UPDATE Nov 8, 2023:

Both Gene Parsons and John York were contacted by e-mail and confirmed that the track is by the both of them and Clarence White. McGuinn's participation is not confirmed.
