Classical singer Carly Paoli has topped the iTunes video chart with her song in aid of Help For Heroes.

The track Liberty, which knocked chart superstar Drake off the top spot, features the Invictus Games Choir, a community choir for serving and veteran personnel from all services, who are wounded, injured or sick, to help them in their recovery.

Paoli said reaching the summit was particularly important because of where the proceeds are going.

“I am over the moon that the first time I achieve a number one hit is with an amazing song, Liberty and that I recorded it with my wonderful friends from the Invictus Games Choir,” she said.

“What makes it even more special is that because proceeds from sales are going to Help For Heroes, it is testament to the fact that people are enthusiastic about supporting a good cause – in this case the brave men and women who have been affected by their service in the Armed Forces.”

Proceeds from the sale of the single and the video will go to Help For Heroes, which supports the choir.
