I reckon "c" for "clubs" is perfectly legit - e.g bridge notation (7C = 7 clubs)....

With all the hints, #2 must be "monetary" (about money, i.e. about ready (cash)).

I'm ok with feeling = atmosphere = blue...
But why is ready = cash?

Correct Rog, and thanks for finishing it off.

Denis, ready money or "readies" used to be a common expression for cash: I did not think that it was a peculiarly British term, but perhaps it did not make it across the Atlantic. http://www.businessballs.com/moneyslanghistory.htm (several clue possibilities there)


Those last two took us a while to figure out even when we had a few more letters.

Merry Christmas or whatever else you may celebrate!
