Just thinking about how momentous it is for a band to still be as successful as these guys are after 40 years is staggering. I bet when Glenn and Don were talking about forming a group together as they supported Linda Ronstadt in 1971 when they were in their 20s, they never figured they'd be playing stadiums when they were in their 60s. It's no mean feat.

Of course, what's really important is not how successful they are after all these years, but all the lives they have touched in that time, and all the lives they continue to touch - myself among them. Glenn has talked about the "soundtrack to people's lives" and he's talking not about thousands, not about hundreds of thousands, but about millions - and that was just the 70s. How many more since then?

What a gift.
