Manhattan Swing Orchestra is a British big band ensemble based in London's West End, serving as the house orchestra for "The Rat Pack at Christmas" since 2002. The orchestra backs three lead vocalists - Stephen Triffitt as Frank Sinatra, Mark Adams as Dean Martin, and George Daniel Long as Sammy Davis Jr. - in a show that recreates the sound and atmosphere of the original Rat Pack concerts. With a brass section built around saxophone and trombone solos, the orchestra has performed at major venues across the UK and internationally, from Cadogan Hall in London to the Royal Concert Hall in Glasgow.
The show "The Rat Pack at Christmas" with Manhattan Swing Orchestra is announced for Cirkusbygningen in Copenhagen on November 30 and December 1, 2026 - the orchestra's first performance in Denmark in many years.
In December 2025, the orchestra performed at Symphony Hall in Birmingham as part of the 23rd tour of "The Rat Pack at Christmas".
The show returned in December 2025 to Cadogan Hall in London and Glasgow Royal Concert Hall as regular venues on the British tour.
