I haven't realized before that Don Felder answers question in the Internet. This one is interesting. If it has been discussed here already, I couldn't find it. Now that Don has finally said this himself, I wonder how many YouTube guitar fans who think this is Don Felder's best solo (and instist that it's him on the original), will dislike the solo from now on.
In his book he cleverly avoided revealing this, but now he couldn't, ha!
Cody, among others, would like to know whether or not Don actually played the solo on the Eagles’ original recording of “I Can’t Tell You Why.”
"Glenn Frey played the original solo on the record. I played it live for all the shows, on the Eagles Live album, and on the Hell Freezes Over CD and DVD."
