Second shows have been added in Atlanta, Houston and Philadelphia, while a third has been tacked on in Boston.

The tour is expected to hit 40 cities throughout the summer, and possibly another 40 in the fall. The band – Glenn Frey, Don Henley, Joe Walsh, and Timothy B. Schmit – is expected to perform songs from their 30-year career history, including those from their top-selling album, Their Greatest Hits 1971-1975.

At the moment, dates run from May 9 through July 18. Most of the shows take place in the East and South; it looks like the Midwest and West will have to wait for the Eagles to land.

For the first time in their history, the Eagles have an official fan club. In conjunction with Yahoo!, the club, eagles.yahoo.com, will offer members access to premium concert tickets for the upcoming tour before they go on sale to the general public.

Along with first shot at tickets, fan club members will also get access to exclusive audio and video content, concert news, tour diaries and other goodies. Membership is $60 per year.

The Eagles were last on the road in 2002 for a total of 32 shows, grossing $35.4 million.
