I don't know much about them other than what I've read in the liner notes of Essential Pebbles 3 and of the "Hit The Road Jack" compilation. But they were not fake! They were from Granaa, Denmark and they released only one single on the Jacks Beat record label (some of the best Danish beat stuff is on this label!) in 1968. For those who haven't heard it, "To Masturbate" is a deranged psychotic version of "Hey Joe" with slightly different (and mostly undecipherable) lyrics... Apparently the other side of the record is an uninteresting version of "Summertime". The band started in 1964 using the name Les Garcons and playing R&B and disappeared by 1970. Any of you who, unlike myself, can read in Danish or just want to see a picture of the Mad Sound's picture sleeve can check out a great site about Danish "pigtraadsmusik" at
