29 October 1990. It was dedicated to Orbison, as "Lefty Wilbury", the pseudonym that Orbison had used in 1988 in honour of his hero Lefty Frizzell. The album met with less success than the previous one. According to Mo Ostin, the choice of album title came about through "George being George"; apparently Harrison was making a wry reference to the appearance of a bootleg that served as a sort of Volume 2.

The editors also recognise the band as "the antithesis of a supergroup", due to the musicians' adoption of fraternal alter egos and the humour inherent in the project. AllMusic managing editor Stephen Thomas Erlewine has similarly written: "It's impossible to picture a supergroup with a stronger pedigree than that (all that's missing is a Rolling Stone), but in another sense it's hard to call the Wilburys a true supergroup, since they arrived nearly two decades after the all-star craze of the '70s peaked, and they never had the self-important air of nearly all the other supergroups. That, of course, was the key to their charm …" Speaking to music journalist Paul Zollo in 2004, Petty agreed that humour
