I would go for the handshake, Introduce myself as Pan, and ask her how she became so beautiful.

I'd ask her why she doesn't record in different languages more often (French and Spanish in particular).

Ooooh, good question indeed! That certainly requires some pondering. Good idea to be prepared if the opportunity ever somes up.

For now, I'm thinking I might ask LM if there might be another Arthurian text she'd consider putting to music, like she did with The Lady Of Shallott?

Ok...I'd go for the hug, introduce myself as Lejla and hope she remembers the name from countless others who have gotten in touch with her SOMEhow, and ask her if there was any possibility she could personally perform at my wedding (whenever it will be) ... then I can ask her plenty of other questions
