Carrie Underwood and other artists lent their talent for a worthy cause as they performed at U2's World AIDS Day (RED) concert in New York on Monday.

The 31-year-old 'American Idol' alumna gave a haunting performance of her hit singles "Change" and "Something in the Water" at the surprise concert as a response to a personal invitation from U2 frontman Bono.

In a press release, Bono explained how this year's celebration of the World AIDS Day would be different from other celebrations as more people are enrolled to life-saving treatment.

"Today, 13 million people have access to life-saving treatment, up from 300,000 just over 10 years ago. Americans don't know the role they've played in this fight. Tonight's event is to inform them and thank them," he said.

The World AIDS Day concert begins at exactly 7:30 p.m. ET and was held in Times Square. Those who could not attend the concert were able to view it on YouTube as it was simultaneously broadcast live online across the United States.

Unfortunately, the lead singer of the famous band was not able to join the group in their surprise concert because of the injuries he acquired in a "high energy bicycle accident" while he was attempting to avoid collision with another rider at the Central Park in November.

After the incident, he was immediately rushed to a nearby medical facility where he underwent CAT scans and X-rays and a five-hour surgery.

In his absence, U2 friends and popular artists Bruce Springsteen and Coldplay's Chris Martin stood with the band while Bono recovers from his injuries, which include a "facial fracture involving the orbit of his eye" and three other fractures.
