‘The Voice’ … ‘Ol’ Blue Eyes’ … ‘The Sultan of Swoon’: the mythology surrounding Frank Sinatra is overwhelming. A gifted entertainer, screen actor and ubiquitous personality, his real legacy as a pioneer of popular song can sometimes get lost in the clamour. This Late Night Prom celebrates the centenary of this musical legend in a concert that brings together some of the great voices of our own time, led by the multitalented Seth MacFarlane. Join John Wilson and his orchestra for an after-hours sequence of big tunes and even bigger performances.
