Justin Bieber's unaired SNL skit has finally been released.
And there's a good reason it didn't make the final cut: it's the "greatest trainwreck ever."
At least, according to Bill Hader.
The "Song for Daddy" sketch features J.B., Hader, Fred Armisen and Bobby Moynihan as a country western band with a very strange song. The 19-year-old pop star plays Hader's son and keyboardist in the musical group.
