Note: the answer to 23d is ''dance'' and 50% of the answers are types of dance such as Do-si-do, Excuse me, Flamenco and ''canary''. (Yes, ''canary'' is a dance according to Chambers!)
(Thanks to Lady Alex 7d has been successfully answered as seeresses.)
Sorry for the confusion and many thanks for the help - I am desperate to get to bed after a very long day. I like ''olecranal'' as a desription of part of the elbow!
