Just saw you wrote on the Tom Petty page "I suppose I'm a little disappointed that this project couldn't have continued in some form (I have a hot take, for instance, that the perfect new 5th Wilbury would have been Roy Wood, but I suppose there was no way Lynne would have wanted to work with him again), but it was probably good for them to finish before the joke wore too thin."

Not that Roy was going to be the 5th Wilbury, but Jeff and Roy DID collaborate for 2 songs in 1989, one year before TW Vol. 3 came out: "Me and You" and "If You Don't Get What You Want." "Me and You" in particular is fantastic (but see if you can pick out which Beatles song the chorus rips off).

Apparently Lindsey Buckingham was considered as the fifth Wilbury after Orbison's death but it never came to be.

Sad you're taking a break, especially as the next artist was The Move/ELO/Roy Wood which I'm betting you'd probably give 3 stars to but deserves 4. Anyway hope things are going a bit better in your life.
