Further to the above, Onara ha hazukashikunai yo is sung by a trio fronted by the (cross-dressing) comedian Hanya. You can download the song as a ringtone from the official fart site, which pops up from the official site of Piramekino, the TV program the song appears on.
As if Shingo-mama wasn't bad enough, now we have to put up with this turd dancing around doing Para Para moves to an effed-up tune about how you don't need to be shy about farting.
My youngest thinks it's a blast (see what I did there...), but my oldest thinks this guy/girl/it is an absolute retard.
Anything for your 15 mins of fame in the J limelight I guess...
