In 1970 Procol also played the original, and now totally forgotten, Woodstock II 'with John Sebastian and virtually no-one else'. They did storm the Friday night at that year's Isle of Wight , though. Very few British bands, if any, have married rock structures and symphonic arrangements with any degree of success. The Nice should have been prosecuted under the Crimes Against Sibelius Act. And let's not forget Deep Purple's Concerto For Group And Orchestra .
Pomp rock is littered with such travesties.
In Concert album with the Edmonton Symphony Orchestra got nearer than most to pulling it off. It taught us discipline. The Grand Hotel album released in 1973 was perhaps Procol Harum' s last high point. Waiters in tailcoats. Mike Stoller was an easy-going guy whereas Jerry Leiber was much more the pushy Building type.
