7. Bee Gees
The Bees Gees who were first called the Rattlesnakes were formed around 1958. What was first a skiffle/rock-and-roll group, later, in 1957, shifted to harmonizing. There is a story about how the Bee Gees got famous that is believed to be true – the band was planning to lip sync to a record in a local cinema but right before their performance, their record broke so the brothers were forced to sing live. The story is that everybody loved their performance so much, they decided to continue singing live.
