Exactly. And I admit I like the solo songs, but perhaps not as many as now at the risk of losing Eagles songs and I know I'm beating a dead horse but to me LBG Eagles vs solo is no comparison. The version on Eagles Live is the best for me anyway. Plus the line "They write Tim letters - tell Glenn Don's great" is just classic.
I do like the fact of having 4 separate lead singers as you said and the other 3 doing harmony when one of them is singing lead. That's what I love about the band. Tim and Joe aren't just backup singers or harmony singers, they can sing lead too and have great songs to sing. It's like you are getting multiple shows in one concert. When I saw them in 2008 it was like seeing the Eagles PLUS seeing Henley and Walsh solo shows all together.
