Jesse Cale Burkett[1], also known by his username McSwagger or simply Jesse Cale, is a friend of Ray William Johnson who also had a large part to play in the creation of several YFM songs.
First appearing in Tig Ol' Bitties as the voice of Benatar (but he had a talkbox effect over his voice), he went on to voice Benatar in several other songs, including NERD RAGE!!!, HIGH VOLTAGE (Linkin Park Cover), and JUPITER, although only as his singing voice. His latest appearance was in Date Myself.
In a YouTube short, Ray revealed that Jesse could only do YFM part-time, due to having moved to the other side of the U.S.A. Inspite of this, he's still been in a couple of YFM Gen 2 songs.
As stated in a tweet from 2022, he is Pansexual. [2]
For some reason, his YouTube icon is now the default icon, being the letter "J".
