I learn the story, then learn Verse 1, then 1 & 2, then 1 & 2 & 3 etc.I try to sing (often in my head) at every opportunity; at work, when cycling or running, any time when my brain is in neutral. It can't be a good method though; I frequently forget my words! Bernard's night-time & morning method works well for me too. Good luck. John PS Hiya Noreen.
