The incorrect spellling of Shu-bi-dua is actually spelled Shu?bi?dua. Shu?bi?dua was formed in 1973, when frontmen Michael Bundesen and Michael Hardinger joined forces on a radio show. Their first album (dubbed Shu-bi-dua 1) came out in 1974, and they kept producing records more or less every year through out the seventies and eighties. The band has gone through a lot of changes through out the years - at one point Bundesen wasn't a part of the band, and these days Hardinger is living in the USA.
Shu-Bi-Dua is still a very active live band, and they still produce a record once in a while. To date Shu-Bi-Dua's discography is getting close to 30 albums.
