This one really is a classic of the genre. The singer's insistence on using just the one note throughout and the musicians' insistence on not hitting any note with anything approaching accuracy results in a cacophony that leads the listener to hysterical giggling or just hysteria within seconds of the play button being pressed.
According to the sleeve, profits from the sale of this record will go to charity. I'm not sure how that is going to work. I think those responsible for this unique musical vision may earn more for those in need by threatening people into giving them money. Something along the lines of, "If you don't give lots of money to my chosen charity I will play you this record."
