Let me see.......

to 1: There is the song which reached a point where the story could take a number of routes to the finish, so I decided to sleep on it, as one does. 27 years later I found the scrap of paper with the first few verses, could remember nothing about what the original story was and where it was supposed to go! So I slept on it again but this time, whilst I slept a verse occurred to me and so I was finally able to finish the song!

to 3: There are a couple of songs which resulted from seeing films. In the first case a verse came into my head whilst I was working. The problem was, this verse was in the middle of the song so I had to write in both directions!
The other song hit me on the way home from the cinema.

I started off writing pseudo-traditional songs but that slowly came to a halt after I left the UK. $0 years later I'm still getting around to premiering some of those songs from way back when even though my audience may not fully grasp what's going on!
