I think all of the Wilburys material is due for a revisit and a re-release. It's quality music, well-played and well-recorded that has a great vibe to it. I think people who missed it the first time around would be pleasantly surprised at how well it holds up over the years. "Tweeter And The Monkey Man" is one of the better sounding Dylan tunes of the past 30 years.
I seriously think the Wilburys worked because there was nobody in that band who was starstruck in that company of musicians. The only one I'd think any of them might defer to in terms of acting like a fan as much as a contemporary would be Roy, because each of them loved Roy's music from the time he was still cutting records on the Sun label, rockabilly tunes like Ooby Dooby and others. But I don't think any of them felt like they were in a pressure situation, I think they just came together out of the sheer joy of making music with each other. And the guy who admits to being awestruck at times was Jeff Lynne, yet his production chops may have been the thing he had over the others. So it worked.
Wings, I think, could have had more of a wide-ranging legacy if not for the fact that they really were not all that consistent in their output. I don't mean musically, but rather in a branding sense. Look at the 70's output from Paul, and where there were classic songs that struck a chord with listeners it could have come from a Paul and Linda album, a Wings album, or something in between where even the Wings lineup was never really a constant thing. Was "Wings" that people bought on "Band On The Run" the same Wings who did the live tour and album? When someone hears "Another Day", do they think it's a Wings song? Paul, Denny Seiwell, and Linda are on it, but it's not Wings. Yet that same lineup with the other Denny was Wings. Or was to be Wings. Then there was McCartney 2, was that Wings like Back To The Egg? or was it a Paul and Linda affair like the first album called McCartney?
It just seemed like the brand was never really established, other than McCartney being the focal point. Maybe it's just me...maybe I'm amazed...I don't know.
