Hi Karen,
I don’t know about the part you’re looking for but I think I saw Mr. Wooldridge’s Introduction & Allegro for two harps at the Virginia Harp Center in Midlothian, VA. In 1970 he and I played the World Premier of that piece together at the Beverly Wilshire Hotel in L.A. He had big hands and his parts seemed to really give you a stretch! At the time he was Manager of the Hollywood Lyon Healy store where I bought my first gold 23. He was sweet, patient and a fine harpist. Good Luck!
