Just seen this thread.

I guess a lot of us have had the experience of hearing a song a couple of times & then having it stick fast, to the point where the only way you can get it out of your head is to learn it, work it up & sing it out (and hopefully pass on the infection!). This has happened to me several times with songs on both John's albums. What's different about John's settings is that it's really hard to do them anywhere near as well as he does. John's delivery isn't at all flashy; you don't sit there thinking "what a range!" or "what amazingly precise pitching!" But if you try singing Craigie Hill yourself, you realise what John brought to it fairly quickly.

John - I hope to see you at Bollington! Is it time to give Jozeph another prod, do you think?
