In 1958 a school band The Jokers was formed in Haarlem. Members were Hans Alta (bass), Rein van den Broek (trumpet), Tim Griek (drums, he was the producer for the first Brainbox album, he died in a car crash in 1988) and Huib van Kampen (guitar/saxophone). They played covers of well known songs. In 1965 the name was changed to Incrowd. In 1967 the name had already changed to Ekseption because there was another Dutch band with the name Incrowd.
