The concert, which will support youth charity The Prince's Trust, is this year's Huawei Winter Concert, sponsored by the leading global information and communications technology (ICT) solutions provider.
Paige and Henshall will be joined by the City of London Sinfonia conducted by Michael Collins and Chris Egan.
In a press statement, Paige commented, "I'm thrilled to be sharing the concert stage not only with the City of London Sinfonia, but also the wonderful Ruthie Henshall – another first for me; but most importantly I’m delighted to be supporting The Prince's Trust."
Henshall also said, "I have always been a fan of Elaine and had the utmost respect for her, so to finally sing with her is just a privilege and a highlight of my career. I can't wait! And to do this together for such a noble cause is the cherry on top.”
