"Happy Birthday to You" entered the public domain in 2016.It was a surprise to see Ernie and Bert's "Happy Birthday to U", since he basically sings the copyrighted "Happy Birthday". I don't know if it counts as parody to replace "you" with "u". Then again, I think I read that the songs lyrics officially lost their copyright status a few years ago.
