Thanks folks, so far we've got 1, 3, 8, 9 and 10. Only half in nearly 24 hours is a bit slow for The Mudcat!

Here's fuller answers for these, as a summary.

1. Yew ("Leaves of Life" or "7 Virgins")
3. Oak ("Sprig of Thyme" or "Garners Gay" / Misc. incl. "Cruel Mother", "Cruel Sweetheart" songs)
8. Apple ("Going to Banbury" / "Wassail Song")
9. Thorn ("True Thomas" / "riddles wisely expounded")
10. Mulberry ("Mulberry Bush" / "Jennifer Gentle" or "2 Magicians")

Keep trying with the rest. No. 2 should be easy ... there aren't too many Shakespeare songs in DT!

Cheers!
Ian
