It is not a "farewell" tour, but The Who says their upcoming 50th Anniversary Tour may be their last major run.

Singer Roger Daltrey says, "This is the beginning of a long goodbye."

But, Daltrey adds that this tour will likely be the end of their big runs:

"We intend to go on doing music until we drop, but we have to be realistic about our age.  The touring is incredibly grinding on the body and we have to draw a line in the sand somewhere.  This will be the last old-fashioned, big tour."

The band announced a string of dates in the UK.  The concerts will start at the end of November and run through December.  A North American run is expected in 2015.

The Who will also head into the studio this summer to record a new album.  Guitarist Pete Townshend gave a hint to the sound saying it might be "more prog rock than pub rock."
