I think the songs "Wish You Were Here" and also "Fanny" were pretty popularized by Eddie Fisher, back in the day. People tend to forget what a wonderful singer he was in his prime. My folks used to play some of his records, and he had a lovely voice.
Songs from his shows were covered on tv shows like "Your Hit Parade"; I once asked my Mom how "I Say Hello" from "Destry Rides Again", and she was able to sing it to me, and she hadn't seen the show itself. There's a video on YouTube or elsewhere with original star Dolores Gray singing in her wonderful, huge but velvety voice.
