Hi Jono
I did wonder if Paul had something to do with some of the Quick crosswords last week. I've thrown away 16,681 now so cannot check. We actually do the crosswords in the paper. Many of the answers seemed more appropriate to a cryptic than a quick. Some days it took us a long time to finish, but then they went easier again to the end of the week.
I'm still hoping for a hint for 16d. Can you confirm that 13d is a specific piece of dance music - a waltz I think.
