They were originally formed in 1998[1] by Daniel Wylie and Stephen Fleming, and later they were joined by Mark Brown, James Clifford, Gary Cuthbert and Paul Docherty.
In March 2002, founder member of Cosmic Rough Riders, Stephen Fleming added lead vocals to his duties when original singer, Daniel Wylie, left to pursue a solo career.
The Cosmic Rough Riders have performed at major UK music festivals including Carling Weekend, Glasgow Green and T In The Park.
When they made a special appearance at Glasgow Barrowlands as part of a show paying tribute to the Scottish singer-songwriter Frankie Miller, they were joined onstage by Joe Walsh (Eagles).
He played guitar on the track "When I'm Away From You", recorded by Cosmic Rough Riders, and released on a Frankie Miller tribute album.
