Joe, your friend has copyrights for his lifetime, and did before the Sonny Bono Copyright Extension.

"Peter and the Wolf" was a a favorite children's program for many community orchestras, and I am sure it is no longer used as much, due to costs. The irony with the Martha Graham copyright issues is that if many of her choreographies are not recreated now, they may actually be lost forever because they are not definitatively notated, and, with the passage of time, it will become impossible to reconstruct them--

Another "thank you" to "T" for keeping us up to date on this, as depressing as the news is.
