>>>"Dolly, I know the director was a nightmare, but most reviews noted that Stamos and Gershon could not sing the parts well and had little of the necessary stage presence."<<<
If the director/choreographer had done his job, he would have drawn performances from the principals and their performances might have worked. I saw the show twice and felt strongly that Stamos could have been fine in the part had he been given real direction. The "Put On You Happy Face Number" was ludicrous in its staging. It was obviously created for the talents of Dick Van Dyke or Donald O'Connor.
There was enormous animosity backstage in that show and it carried over the footlights.
Don't judge Stamos or Gershon for the mess that was on stage. They were left at sea by an absentee leader.
