Well done so far. Here's a brief summary of progress.Nos 5, 6, 8, 9 and 10 you've essentially got. I was thinking of Holly Tannen for the Appalachian Dulcimer, though.
Of the others
1. Good so far, but what's the connection with Hugh Roberton? Get this and you've got the song name too!
2. Bitter Withy is it, but where did it come from?
3. Jenny Lind is right, but why didi she stop singing opera?
4. Most of the answer to this is in a recent thread. The answer's a Scottish Geordie!
7. OK so far, but what was Topaz's special characteristic as a poet?
Full explanations when you get all the answers!
Good luck!
