Their early stuff was outstanding. Later stuff was good too, but commercial, the hard edges of the early work "blanded" down to accommodate the tender sensibilities of the American masses. Still, one of the best concerts I ever attended was at the Palladium Theatre in NY, in 1979, I think, or maybe 1980. The Clash, the Undertones (an Irish punk band), and Sam and Dave all appeared on the bill, and it was one of the best times I ever had at a rock concert.
