I find it hard to believe that Jon didn't know this song before hearing Little Angels sing it.
Jon is a big fan of Creedance Clearwater Revival, because Travelling Band is one of their songs which the band covered LOADS of times in the 80's and he also sang Proud Mary at the Carlesburg Concert which is one of their songs.

It's a shame Little Angels split up because they were one of the only decent rock bands from the UK in their time.
