Beach Boys mid sixties in Cleveland- Glen Campbell was touring with them and sang the high parts. The Lovin' Spoonful was the warm up band. The Beatles in 1966 may have been the same year or a year later. The best early concert, however, was Genesis Selling England by the Pound concert at an old, beautiful movie theater downtown Cleveland, tenth row center-probably not more than 500-1000 people there. They were using SAE amps! Killer concert-early 70's.
