After Weird Al decided to write a parody of Lady Gaga’s “Born this Way”, he asked her consent to do it as a courtesy. She made him record a version she could listen to before she gave him an answer and then she said no. Read the whole story on Weird Al’s blog.
Al doesn’t need her permission to release it but he won’t out of respect, but it’s holding up his new CD. Fortunately, he decided to put it on the internet.
UPDATE: Now Lady Gaga has approved it, saying her manager never sent her the song and was the one who disapproved it. Weird Al is happy, free press for his CD and song.
