BS&T headlined at major venues around the world: the Royal Albert Hall, the Metropolitan Opera House, the Hollywood Bowl, Madison Square Garden, and Caesar's Palace, as well as the Newport Jazz Festival and Woodstock. It was the first contemporary band to break through the Iron Curtain with its historic United States Department of State-sponsored tour of Eastern Europe in May and June 1970). In the early years Clayton-Thomas lived on the road, travelling all over Europe, Australia, Asia, South America, the US, and Canada with BS&T. The constant touring began to take its toll. Clayton-Thomas left the band in 1972, exhausted by life on the road. By the mid '70s, the founding members began to drift away to start families and pursue their own musical ambitions.
