Rocker Stephen Stills has spoken out about the aborted Buffalo Springfield reunion tour for the first time, revealing bandmate Neil Young left him "in a lurch" when he scrapped plans for a proper get together.

Young reformed his old band after 42 years for a 2010 Bridge School Benefit concert and a handful of other shows.

The group had planned to tour North America, but the trek was initially put back and then scrapped as Young embarked on a new project with his former backing band Crazy Horse.

And in a new interview with Rolling Stone magazine, Crosby, Stills & Nash star Stephen Stills admits Young's decision not to tour presented huge problems for his bandmates and crew.

He says, "It left me in a lurch for three quarters (of 2011) and ruined my financial planning. Also, 150 people got laid off that were supposed to work on the tour.

"We didn't go to all that trouble for seven shows. That's what impetuosity will do for you. You can't go off half-cocked... When Neil is involved, you need a seatbelt."

But Stills insists he can't be angry with Young: "He was very kind to me in his book. I can't be unkind about it... Working with Neil is a privilege, not a right."

And he still hopes that Young will reconsider a Buffalo Springfield tour: "There is the seed of something great still there (and) it's worth exploring again."
