VIDEO: Michael Ball and Alfie Boe Perform at the Royal Variety

Iconic pair Michael Ball and Alfie Boe took to the stage at the Royal Variety this December to sing a heartfelt duet of 'The Prayer'. They then closed the show with 'Bring Me Sunshine'. Watch the performances below!

Ball and Boe are two of the most cherished performers in the UK, with two of the greatest voices. Between them, this legend of musical theatre and Britain's most popular and best-selling tenor, a favourite of the Royals, have achieved accolades and triumphs galore.

Michael Ball has won critical and public acclaim over the last 25 years with his dynamic, award-winning lead roles in the West End and on Broadway. He is a double Olivier Award winner, multi-platinum recording artist, top-selling live concert performer, and a hugely popular radio and TV presenter who's made box-office history. Michael's many West End credits include originating the role of Marius (Les Miserables), Giorgio (Stephen Sondheim's Passion), Raoul (The Phantom of the Opera), Alex (Aspects of Love, West End and Broadway), Caractacus Potts (Chitty Chitty Bang Bang), Count Fosco (Woman In White, West End and Broadway), Edna Turnblad (Hairspray, West End and on tour) for which he won the 2008 Laurence Olivier Award for Best Actor In A Musical, and Sweeney Todd (Sweeney Todd: The Demon Barber of Fleet Street, Chichester and West End).

Alfie Boe's exceptional voice has made him Britain's most popular and biggest-selling tenor. The Tony Award winner has conquered the world's greatest opera stages and arenas, led the cast of Les Misérables for nearly a year, stole the show at the Queen's Diamond Jubilee Concert at Buckingham Palace, and performed at the Queen's 90th birthday celebrations at Windsor Castle. Boe is a fan of both classical music and classic rock - in 2015 he collaborated with one of his heroes, Pete Townshend, on Classic Quadrophenia - the orchestral version of The Who's seminal album. He was chosen by Townshend to perform the lead role of young mod Jimmy, thrilling audiences at the Royal Albert Hall in London and in Vienna, with more dates to come. Always striving to bring good music to different audiences, Boe has performed three sold-out tours for hundreds of thousands of fans across the UK, and has notched up four Top 10 albums, selling in excess of 1.5 million copies in the UK.
