Sheryl Crow Not Flying With Fleetwood Mac (E! Online)

Los Angeles (E! Online) - Sheryl Crow and Fleetwood Mac have stopped thinking about a shared tomorrow.

Just as frontman Lindsey Buckingham was confirming that his bands 2009 tour would proceed without the All I Wanna Do songstress, Crow came full circle on the rumor that she started in March, when she told a music website that she and the 70s-era hitmakers definitely had plans to collaborate.

No, that was those Rumours--to quote the album, the singer-songwriter told a group of Nashville college students Wednesday at a Grammys Foundation QA session when asked about her future Fleetwood plans.

Im a huge fan and have a great relationship with Stevie [Nicks], and actually with all of them. I just absolutely adore them, added Crow, who has produced for Nicks and provided backup vocals and instrumentals for a number of tracks on the Fleetwood den mothers 2001 solo album Trouble in Shangri-La.

She also eased up on the assurances: I think their next album may be while Im on the road, she said. Hopefully in the future well have some kind of collaboration, but not at this time.

Her comment earlier this year left Fleetwood Mac a bit puzzled, with Buckingham telling Billboard.com in March that he and his fellow bandmates were all a little surprised at her announcement.

But hers was certainly a name that has come up. Well have to see, he graciously added.

Now, however, its clear that Fleetwood Mac has decided to go its own way. Buckingham, whos heading out on a solo tour Sept. 7 in support of his upcoming album Gift of Screws, told Billboard.com yesterday that the whole Crow business kinda got out of hand.

Although he and Nicks and the rest spoke with the Detours purveyor, the idea--which partly sprang from the bands belief that there may have been a little too much testosterone on stage when we went out in 2003--just kind of lost its momentum.

Keyboardist and singer Christine McVie left the group in the late 1990s, leaving Nicks as its sole female member.
