gaki no tsukai karaoke specials?

i remember a while ago watching some episodes of the gaki crew doing some karaoke and hamada getting really into it and found them very entertaining. i cant seem to find them on youtube anymore and does anyone kno if they have been uploaded here?
and there was also a “best of” episode tht i saw tht ended with hamada doing a duet with one of his fave singers nd i wanted to kno if tht was here too

thnks in advance

Was this what you were looking for? :) I don’t know if it’s what you were talking about, but they are doing karaoke in this episode.
