This is awesome and has to be so much fun for the students running the program. It's called the "Dial A Carol" program and it's run by student volunteers at the University of Illinois. They've been running the 'Carol Hotline' for 57 years and it's simple - you call and request and Christmas song and then they start singing! According to the University, "last year the program logged more than 10,000 calls. All 50 states were covered within the first 24 hours of the event, and calls were received from 75 countries."

The program runs through December 20th and you can reach the hotline by calling 217-332-1882. Maybe you can even return the favor and sing them a carol back!
