I can remember listening to this every Sunday, when it always got requested on Two Way Family Favourites. I remember once when it had finished, the two presenters (one in England, one in Germany) had a discussion about whether the watery sound effects changed key at the same time as the song did. Having just listened to Kyle's mp3, I think they were right!
Kyle has kindly put it here:Messing About On The River, so you can all have a listen. It's still lovely.
Cheers
