Times 25,618 - Celebrities In Abundance

An easy 15 minute stroll in the park. I need some help with the Minstrel reference at 9D which I solved straight from the literal.

I'm acting as a DJ at a Halloween Tea Dance this afternoon so will be busy today but I doubt there will be many queries. If you have problems please ask and other bloggers will I'm sure help you.
