When Brenda Drumm from Kildare first tweeted about making a Twitter Xmas Single on November 19, there was no way she could have known that just two weeks later she would have organised, recorded and released a No. 1 song. In fact, we were a little taken aback, too.

But the working mum has managed to do just that – with the help of countless musicians, engineers, fundraisers and well-wishers across the country.

A cover of ‘Winter Song’ (originally sung by Sara Bareilles and Ingrid Michaelson) entered the Irish iTunes chart at No. 4 and climbed proudly to No. 1 yesterday. It was recorded last Sunday at the Westin Hotel with the help of 140 people who gathered to lend their voices, studio skills and tea-making abilities.

“I had no idea that anything like this would happen,” she said, “and it really just shows the power of Twitter and the generosity and goodwill in the hearts of Irish people. This is the real spirit of Christmas at work.”

All proceeds from the track – which is only 99 cents to purchase – are earmarked for the Neonatal special care unit at the National Maternity Hospital in Holles Street, Dublin. The choice of charity was also decided by the Twitter community.

The organisers are hoping that the track will be a goodhearted alternative to the less-than-angelic X-Factor Christmas song. You can help the race by downloading the track from iTunes here or help publicise it by trending #Twitterxmassingle among your friends.
