Once upon a time I heard a song called 'How Long Has it Been'. There is a version I think maybe by Jim Reeves but this isn't the one I heard. The version I heard was on a cassette recording (back when you could buy music cassettes instead of CD's) done by a bluegrass band I believe from KY. Does anyone have any idea how I might find a recording of this song?? Or perhaps you might know the name of a bluegrass band that sings it.
