After rejoining civviestreet, Beadle played in several travelling jazz and Big bands of the day including Joe Daniels and his Hot Shots and the Teddy Foster Orchestra.

However his most successful song-writing credit came when he wrote the theme to the children's TV Show The Adventures of Rupert Bear in 1971 together with lyricist Ron Roker.

Due to potential professional and contractual conflicts, Beadle wrote the song under the pseudonym Frank Weston.

Possibly his most-used piece was "Western Panorama"[5] which has been played in TV and radio productions (including Keeping Up Appearances and SpongeBob SquarePants) because of its instantly recognisable "wild west" sound.

His notable successes while MD of CBS Songs include being responsible for helping to launch the UK career of Billy Joel after convincing CBS USA to release the rights to his hit song "Just the Way You Are", being heavily involved with Jeff Wayne's smash hit concept album The War of The Worlds and Art Garfunkel's "Bright Eyes"[8] for the film Watership Down which reached number 1 in the United Kingdom, Ireland and in the Netherlands and which sold over 1 million copies worldwide in 1979.

After leaving CBS, Beadle briefly became managing director of music publishing at MAM Corporation controlling the interests of artists including Tom Jones, Engelbert Humperdinck and Gilbert O'Sullivan.
