Enjoyed this for the first couple of hours, got the circular answers, most of the radials, the theme and the person. Then, as generally seems to be the case with circular grids and as others have mentioned, knocking off the last dozen or so radials took another couple of hours and was a bit of a chore.
Couldn't parse 26 but now have it thanks to Loge's post. Hadn't come across that meaning of vocal before.
