Nick, the whistle tab version does do something a little different but it still works OK.Let me try to explain using Tom's notation. We have (Tom's on first line - dt below)
No-el, No-el, No-el, No-el, Born is...
4565 43 2 60 1 1 2 6
4565 43 2 60 10 61 210 6
I hope I got that right. I've never used whistle tab and haven't touched a whistle in a long while.
