Lighting up joints in the White House, acrimonious arguments, jail time and liver transplants are all part of the Crosby, Stills and Nash legacy.

Since forming in 1968, original Woodstock supergroup CSN have reunited for a new world tour which will keep them on the road until the middle of September.

Thirty-six years on from the release of their eponymous debut album, which brought them instant chart success, they are still rocking.

Switching between acoustic folk and melodic pop, complemented by unique three-part harmonies, their musicianship has always been revered, being probably the only North American band to challenge the popularity of The Beatles in the late-Sixties and early-Seventies.

Hits such as Suite: Judy Blue Eyes, Helplessly Hoping and Teach Your Children sum up an era. CSN had a huge impact on many of those who came of age around that period, tuning in to and addressing social issues in a climate of cultural change.

No strangers to success even in those early days, all members came from brilliant beginnings. Crosby had been a pivotal member of The Byrds, Stills of Buffalo Springfield, while Nash learnt his trade across the Atlantic in The Hollies. Sometime member (CSNY) and fellow superstar Neil Young als dropped in and out.

Their relationships with each other have not always been as harmonious as their songs, personality clashes hampering the output of the band.

Legend has it that when news came through on the radio that Young's album had reached number one during a tour which saw all four travelling in separate buses, Young promptly absented himself by turning around and driving straight back to LA.

Regardless of the fluctuating line-up combinations, CSN have been putting out records and playing live on their own and together for years now.

Between them they now have an impressive discography.

In 1997, they were inducted into the Rock 'n' Roll Hall of Fame in recognition of their contribution to contemporary American music.

Scoring worthiness points, they still speak out in support of causes such as No Nukes, Rainforest Action and Amnesty International and fund-raise through their music.

All CSN members appear purposefully busy Stephen Stills released his latest solo effort Man Alive in June, while David Crosby collaborated on a new album with Graham Nash, which resulted in a tour earlier this year.

If the summer of love means anything to you, spend a night listening to these veterans doing what they do best.
