Sara Mohr Pietsch introduces the EFG London Jazz Festival's opening night gala, live from the Barbican in London. Guy Barker conducts the London Jazz Festival Orchestra in Jazz Voice 2015 - a celebration of some of the great songs of the past ten decades, sung by some of the great voices of today.

Among this year's line-up are Illinois-born R&B singer Liv Warfield; emerging Californian singer-songwriter Jarrod Lawson; New York-based singer and guitarist Becca Stevens; UK veteran Elaine Delmar, who made her broadcast debut in 1952; and younger Brits Joe Stilgoe, Rebecca Ferguson and Nicki Wells with British Indian composer Nitin Sawhney.

The programme of songs, all specially arranged by Guy Barker, draws on major anniversaries, birthdays and milestones that link the decades stretching back from 2015.

In the interval, Ian McMillan presents 'A Jazzy Verb' - reflections on discovering jazz as a young man, and an exploration of the connections between jazz, voice and language (produced by Sharon Sephton).
