Paul Whiteman decided to take the CONCERTO on tour in 1928. It was obviously impossible to travel with the 100 or so players that the immense score required, so Whiteman turned once more to Ferde Grofe. Grofe scaled the orchestration down so that the 30 piece band could handle it, adding saxophones in the process to replace several of the symphonic winds. So, Steve, if you want to verify this data, and listening this other interesting version, just buy the ProArte CD mentioned in my first post. Another comment: this CONCERTO version was recorded on 3 discs by Columbia in 1928 with Roy Bargy playing the solo piano. Keep in touch!
