I don't remember the Freddy Davies song, Mike - saw him on stage once on holiday somewhere I think it was. I wouldn't go out and order a trifle but my Mum's was delicious but that might have been the bottle of sherry she used to put in it!
U Upside Down Cake - even if I say so myself I used to do a cracking pineapple and coconut one in the distant past when I used to bake.
