I thought Ralph's Angie was quite interesting. I love Bert, but his Angie is played too fast for my liking, and, like Bert did with Davy's Angie, i.e. altering things and inserting a different tune ( Worksong?), so did Ralph.
If there's one thing that you must do when playing Angie, it's to never play it exactly - even if you can - like Bert or Davy!
