With the song Christmas Again (The Show Must Go On!), London's West End wants to celebrate that by 2020 is finally over and draw attention to the cycle of people and work if hit hard during the pandemic.
In the video for the song, audience hosts from the West End participate as dancers.
The show must go on is an established mantra in the industry, but has seldom been as fateful.
Mass redundancies have been followed by cautious openings, money invested and new setbacks when the spread of infection picked up speed again in the UK during the autumn.
The authors behind the song, Anna Hale, Joe McNeice and Matthew Spalding, have started a fund where the proceeds for the song are included. The money goes, among other things, to freelance theater workers who lost their jobs during the past year. See a taste of the song in the clip above.
