Blue Peter Music Makers gave 40 young musicians the chance to get involved in recording a new version of the theme tune 'Barnacle Bill'.
The track is one of the best known pieces of music on TV and has been used on the programme since the first ever episode in 1958. There have been lots of different versions of the tune but perhaps the most famous is Mike Oldfield's track from 1979, which was also released as a single.

Demonstration from Mike Oldfield
Mike Oldfield is the man who inspired Murray Gold to become a composer. His version of the Blue Peter theme tune was one of the best loved and included dozens of different instruments, which he all played himself. In this video clip Mike shows former Blue Peter presenter Simon Groom how he put the piece together back in 1979.
