"I ended up doing two passes of the performance because I actually forgot the first line of the second verse.
"I just start over-thinking stuff," he added. "I wrote the song and I forgot the lyrics to it!"
Below are videos of his Ellen performance, plus his amazing in-studio performance with Elvis Duran & the 96.1 KISS-FM Morning Show.
