YOUTUBE BAND - HELP!!

[_sophie_]

I remeber ageeeeeeeeeeeeeeeees ago, I found a cover of a song.. can't remember which one, but it was good. Done by a (i think) japanese band, but they sang in english. I am getting so frustarted not being able to remember it!
So i think in the band there was about 5 people, but im pretty sure in this video on youtube there was only two. One of them was wearing a baseball cap and a red checkered shirt of what i can remember and i think the other one had glasses on. They had a keyboard in front of them and i remember that either at the start or end of the video they had some sort of joke to each other which i used to think was hillarious...
does anyone know the video im describing?
it's one of those stupid, frustrating things that i really want to remember now!
thanks!
