Call it luck or great planning. All four members of Crosby, Stills, Nash & Young will be together again on Oct. 26-27 for the Bridge School Benefit Concert in Mountain View, Calif. The show will no doubt whet the appetite of fans of the band, especially those anticipating a 40th anniversary tour in 2014.

Stephen Stills talked to the Boston Globe about a potential tour and while he didn't elaborate on any 2014 plans, he revealed the reunion date for this fall. Neil Young News points out that stars seem to be aligning for something bigger. Neil Young recently cancelled tour dates with Crazy Horse. Stills covered 'Rockin' In the Free World' with his new blues band the Rides (to rave reviews). And the much-talked about live album from 1974 was pushed back to coincide with the 40th anniversary.

David Crosby, Stills and Graham Nash played 23 shows together this spring and summer, including 10 in Europe. This fall's concert is the 27th annual Bridge School benefit. Young and his wife organize the acoustic charity show, which this year will also feature Heart, Queens of the Stone Age, Elvis Costello and many more. Tickets go on sale Sept. 13.
