I just watched it. It's a pretty solid cover, and Johnny is hilarious, as expected.
Johnny living his best life. The cover is pretty cool though!
It's pretty faithful, but it sounds good. I could do with better vocals, but the music is tight!
Jammin! My jaw dropped when he just tossed his bass at the end but im sure he has just a few more. 
It was very carelessly/carefully. I'm sure it's a road bass that's already banged up, and he tossed it somewhere it would land reasonably safely.
