i don't know, but we were always told then that it was his first performance (the one in chicago); that was a festival for the benefit of the then Chicago Ballet, and wasn't connected with Geneva.
I tried some googling and found a site that lists this:
"1977: Title role in The Prodigal Son (Balanchine), International Dance Festival of Stars, Chicago"
But who provided the ensemble for him, even assuming he only did excerpts? Perhaps that's where the Geneva Ballet came in.
Another interesting tidbit on that list:
"1974: Title role (cr) in The Prodigal Son (Murdmaa), Baryshnikov Choreographic Evening, Leningrad"
I remember from some biographical reports that he staged one of these special evenings (a one-time-only performance) in the spring before his defection. If that list is accurate, then it appears he had some serious interest in this role, even by a different choreographer! (Who is Murdmaa? Did he "borrow" the Balanchine version?")
