Thunderbirds (1965)

This is the 1965 Supermarionation original, not the 2015 remake Thunderbirds Are Go. Gerry Anderson asked Barry Gray for a military feel, and Gray answered with The Thunderbirds March, a brass-heavy piece that follows Jeff Tracy's famous countdown. It is a proper march, with bold brass and a tune that climbs like a rocket leaving its silo, and it is one of the most satisfying TV themes for a band to play. Gray was musical director on all of the Andersons' productions from Four Feather Falls onward, and this is the theme that best shows why they kept him.
