I've had an answer from the D&S so, if anyone else is wondering, the missing clues are
19d. Point reached in acting career. 21d. Don't stand for falsehood.
I think it was Stage and Lie but I gave the paper to a friend as there was a photo of a member of his family in it! I just thought that some other ABers may have wondered about the missing clues. Many thanks fiction-factory for your response.
