Hi woodijon - your initial 'L' in 21a was wrong - "Club Tropicana's fourth, say" - Putter (club) - '(troPicana['s 4th]) + 'utter' (say) The word 'daubing' in 21d is an anag indicator, as in "to smear" (the letters)
Aha! Thanks Lie-in. When I read your first answer I thought you agreed with Lorrain - which is why I couldn't understand your logic.... Now you have revealed my error with21a all is clear. Many thanks!
