Just a minor point: Opus19/The Dreamer has been seen at Covent Garden, New York City ballet brought it shortly after it was premiered in 1979 with the original cast - Patricia McBride and a somewhat disengaged Baryshnikov who announced his departure from NYCB not long afterwards to direct American Ballet Theatre, It entered the Royal Ballet repertoire in the 1986-87 season. Cynthia Harvey danced the McBride role and I guess it was Dowell in the principal male role, though I have no memory of him. I do however recall Harvey being quite lovely in the ballet. I think that it lasted only one season - but I can't be sure of that.
