I saw the post in the Post-Rumours forum, but I think I'll respond here in Christine's forum. I always check this board first too.
"All Over Again" is definitely her farewell to the band-"breaking the chain", "drifting away", etc. It's a beautiful, but sad song. I think her songs on Time may have been her most personal songs on any Fleetwood Mac album, especially "All Over Again", "Hollywood" & "Nights In Estoril". It's easy to understand why she left the band a few years later after listening to these songs.
By the way, I like, but not love Time. It's a lot better than it's given credit for. I really like Christine's & Bekka's songs. Bekka can really sing. But, I'm not too fond of Billy's & Dave's songs. That's pretty unusual for me regarding Billy's songs. I pretty much like everything from him that I've heard, except for his Time songs. I DON'T like "These Strange Times" at the end, though. They should have dropped that track & ended the album with "All Over Again".
