Czech hard-rock/metal/punk group, specialized in remakes of well known hits, tuning them up with rock/metal sound and original explicit lyrics, which are usually about sex, getting laid, going to the toilet, getting drunk and pubs. The band consists of 4 members: Mikesh(Guitars), Ketchup(Bass), Filipes(Drums) and famous classical singer Yetty(vocals). Their concerts are very atmospheric and friendly, they often wear very strange clothes like female dresses etc. Their name could be translated as Guinea Pigs on A Loose.
