Sorry, crofter, I didn't see your previous answer of spin doctor and I like it as well. I'd thought of lark but it doesn't quite seem to fit the clue. It may well turn out to be the answer wanted so thanks for confirming my idea.
juliefer I agree with your general feelings about LARK - it's a bit weak. I'll give both of these some more thought if you like.
As for Spin Doctor - I only meant that I hadn't poached it from someone else - not that you should have seen it! At the time, there was some doubt expressed about its corrrectess. Not in my mind though! I like it!
I answered this before for someone.
The sound of the lark is lovely and the other meaning of lark being great fun. So lark is lovely and also fun.
o-ice
juliefer You don't seem to appear much on AB, but when you do it's always with a relevant point to make -and with a h**l of a punch! (Just a personal observation)
