Idina Menzel

You may or may not remember that name from the time John Travolta didn’t say it at the Oscars (‘Please welcome the wickedly talented, one and only Adele Dazeem’). Of course, she was at that ceremony to sing the Oscar-winning ‘Frozen’ number ‘Let It Go’ – a song that’ll be the backbone of her current performing setlist, which’ll also likely include songs from ‘Wicked’ (she was the original Elphaba), ‘Rent’ (the original Maureen Johnson) and ‘Glee’ (she played Rachel Corcoran’s mother, Shelby), not to mention her own healthy back catalogue as a singer-songwriter.
