The indication from the article was that Ron and Frank have recorded additional parts for music on the album. At no stage was there any specific indication made that they were re-recording anybody else's parts, they were simply adding to what was there, whether it is a complete track or a new track Axl recorded this year or something
Agreed.? I got that they participated in recording for the album.? Anything beyond that, in my opinion, is more speculation and rumor.
Well FWIW, I met Ron after the show in Ottawa (he was very cool, came over to spend some time with about a dozen of us who had waited out back of the arena after the show) and I asked him if he is playing in any of the songs on the new album and he said "a few."
Nothing earth-shattering there I'm sure, as you said, I believe it's widely known he is on the album, but I definately got it right from the horses' mouth.
I didn't press him to elaborate if he had re-recorded parts or if it was new material, but there is no question he is on the new CD.
