I know people have their favourites and you can tell I'm no exception
but from my perspective of being a Don Henley fan from the 80s, I had no idea he had been in the Eagles. I didn't know Glenn save a few performances on
Miami Vice. It had been 14 years since they 'took a break' so Don
would have been the best known to a new generation from his hits. Of course they weren't to know that the diehard Eagles fans would always stick by them but if they were unsure of how they would be accepted then they had to showcase their most well known star and that was Don Henley. I think HFO was brilliant and Don was undoubtedly the star for the reasons I've outlined. Subsequently, of course, once they saw how the fans reacted to them, they were able to gain more confidence and showcase all the members. However, I don't think you can blame Don for his prominent role.
I know friends of mine who have barely heard of the Eagles when asked only recognize
Hotel California and Don Henley, they haven't a clue about any of the other members including (and I know some people won't like me saying this - Glenn). Not everyone is committed to their favourites as we are, I'm afraid.
