Singer Gary Barlow is feeling “nervous” about the West End opening of the musical “The Girls“.

The previews of the show will start here in January.

Barlow, who has co-written the musical comedy with Tim Firth, says he is already getting worried about the response to the show when it opens in the capital, reports

Replying to a fan who told him that she had bought tickets for opening night, Barlow posted on Twitter: “Nervous already xxx”.

Barlow is grateful to all his fans who have purchased tickets for the production’s West End run.

“Thank you to everyone who’s booked tickets to see ‘The Girls’ musical and no booking fees,” he tweeted.

“The Girls” is based on the play and film “Calendar Girls”, which itself was based on a true story about a group of women who made a nude calendar for charity.
