From https://www.rollingstone.com/m...eartbreakers-730187, it appears as though Tom Petty and the Heartbreakers' "Free Fallin'" made the list of rehearsal songs being considered for Fleetwood Mac setlists, as did Crowded House's "Don't Dream It's Over." "Oh, Well" was also included, but with vocals from Mike Campbell, as Neil apparently felt that they required more of a bluesy touch than of which he was capable.
The first Fleetwood Mac tour date is now only three days away, so more on the setlist topic should be known soon.
