EDVARD GRIEG, Norwegian composer (d. 1907); Edvard Grieg? That sweet little guy, the one whose “Anitra’s Dance” is always played in third grade music appreciation class? What’s he doing here? In old age he was completely taken with the boyish charms of curly-haired, blond Percy Grainger, whose “Country Gardens” is inflicted on the same third-grade class of audiophiles. “I love him,” Grieg declared, I love him like I love a young woman.” That’s odd. That’s exactly what Vachel Lindsay said about the same guy! Mercy Percy!
