These guys play humorous, mainly cover versions of famous pop and rock hits using the fast and hilarious beat of humppa (trad. Finnish polka-like dance).
Current members of the band are Onni Varis (keyboard, vocals), Petteri Halonen (keyboard, guitar, vocals), Lassi Kinnunen (accordion, vocals), Martti Varis (bass, vocals) and Tapio Santaharju (drums, vocals). Ilmari Koivuluhta (sound technique, logistics) and Pekka Jokinen (graphics, merchandise) are completing the humppa family. These are not in fact their real names; their (fake) first names are their second names, and their (fake) surnames are their mothers' maiden names. Onni Varis and Martti Varis are in no way related, both of their mothers' maiden names just happen to be the same.
