The Shepherd's Song

We were talking about jazz tonight and Dad was remembering going to to see "trad Jazz" in Britain in the early 60's. Dad got one of his favourites out and played us some Acker Bilk. We then bounced around music genres for a long time and I then played one of my favourites of the day - Pete Doherty. So as Pete's singing, I pick up the Acky Bilk CD and I'm scanning the song titles and just as I'm reading the title of track - The Shepherd's Song, Pete sings "as simple as The Shepherd's Song". Wow.
