Thanks, Will!
The ABBA clue I had run down all sorts of rabbit holes as was intended. And there it was, in plain sight!
In the second clue I guessed how the end 2 letters worked but couldn't see the tool.
Just that pesky XxX clue now but enough has been said about that, so I'll think on.
Ps - in my head, your user name indicates your date of birth. So I picture you as a razor sharp 87 year old. No need to confirm or deny.
