I always considered a "nostalgia act" one who had no new material, who toured solely working from their back catalog and included nothing original in the set that was less than ten years old. Indeed, many nostalgia acts don't play any original songs less than THIRTY years old! Thanks to LROOE, the Eagles are not that.
Regarding iTunes and revenue from downloads, here's a 2008 quote from the Wall Street Journal :"Irving Azoff, the manager of numerous high-profile acts including the Eagles, says that a few years ago he presented the band with a financial analysis showing that their royalties to date from iTunes sales were far lower than anyone expected.
Guitarist Glenn Frey did some back-of-the-envelope math of his own. 'His comment was that it amounted to 39 minutes on stage in Kansas City,' Mr. Azoff recalls with a chuckle.
Though Mr. Azoff didn't disclose the royalty figure, Mr. Frey's off-the-cuff analysis implies the band had received less than $500,000 from its iTunes sales at that point. The band's iTunes income has increased since then, Mr. Azoff adds. Nonetheless, he says: 'I'm underwhelmed by the number of sales I see on iTunes for the classic bands.'
That sentiment was a factor in the Eagles' decision to sell their latest album, 'Long Road Out of Eden,' only through Wal-Mart."
