Thanks Geeker and Rocky
I got the washing in, but it was cold out there now, so I've put off my pricking out until tomorrow morning. What a lovely day it has been here in the south west. I'm very jealous of your walk Rocky. Unfortunately, I have a bad back and am now finding walking painful. I have to pace myself. But lunch outside was delightful - the first of this year, despite the noise from the M5 when the wind is from the south east, which it always is with high pressure.
I think I've finished. I've got answers for both 1d and 11ac. I wasn't sure about 11ac as I couldn't find the shop, but thanks Geeker I see it now. That just left me with 1d. I've got an answer that fits the definition, but I still have no idea who the singer is. My GK around singers matches my GK around football. I've just worked out the parsing for 4d. I still can't explain the parsing for the second word in 3d. I had trouble with 16d as well, but that may be because I don't play golf.
I don't usually like Picaroon, but I enjoyed this one - some stunning clues. As I said earlier, my COD was definitely 18ac which was also my FOI, my LOI was 1d.
