Thanks Brendan et al
Jono, you nearly threw me with the wrong letter in 14d as I knew it was right.
Since my last post, I got 1ac. I knew the name, but had never understood the definition. I've also had trouble with the band member, but as someone suggested I googled it. I'd never heard his name, despite my age.
I had also concluded what the answer to 27ac was, though was misled by an earlier thread that suggested it had 8 letters. I'd never heard of it used this way, but google has confirmed it.
But I still have 4 left. They are 1d, 11ac, 18ac and 23d. Any hints for these would be most welcome.
