I too have bought the 3 DVD boxset. Fantastic stuff. The band's catalogue of songs and their vocal harmonies are wonderful.
I have to agree re Glen Frey and Don Henley, BIG egos, with Frey's being incredibly over inflated - he comes accross as a real dick.
Its interesting to see how the members have aged. Randy Meisner is practically unrecognizable from his 70's persona, as is Bernie Leadon due to the loss of his trademark curly hair. Joe Walsh is looking good, but his voice has the tell tale slurring to mark the many years of indulgence.
Don Felder looks fantastic. I guess being removed from the stress of the Eagles environment has been good for him? Have you read his biography "Heaven and Hell"? That's a good one, aven after Frey and Henley's laeyers did their best to neuter the content.
