I've just got the theme and title and am, as usual, thoroughly enjoying this puzzle. The three different types of clue were a challenge to start with but it all works out very nicely. Many thanks for the entertainment, Ron.
haggis58 - a full understanding of the theme will lead you to sufficient cross-checking of those clues to limit the number of possible answers and allow of back-solving.
Tramart - thanks for your response. I thought I did have a full understanding of the theme but can't work out the down clues that I have missing in order to fill the last three rows. All I have so far is: -va---o-nke- in 1st row then -ef---a-lex- in 2nd row and -st---d-ipe- in 3rd row. Very frustrasting! Do three children's names appear in 1st row and does the main performer feature in the 3rd row?
Tramart - thank you for your inspiration and encouragement. Have now completed the grid and justified all my answers except 22ac. And why the arrow at bottom right of grid?
