Everyone talks about how “Happy Birthday to You” is heavily copyrighted, but no one talks about how it sucks. It’s lyrically and melodically repetitive, and undeniably hack. Don’t worry, as is often the case, Stephen Colbert is here to save the day. After being forbidden from singing “Happy Birthday to You” to “Happy Birthday to You,” in honor of its own birthday, he offered his own song. It’s much better and decidedly much more challenging to sing.
