That was good fun, working out where the letters should go. I like 1 and 39 too (once I'd looked up boondocks!) also 3 and 4. Also now know how Canasta is played.
I like puzzles based on quotations- have only ever finished 3 Listeners (don't even start them now), one based on an obscure quotation. Once you guessed it (and looked it up) from the letters you had, the rest was (relatively) easy.
Thanks syzygy and sunray.
