For you singers - hardest Stevie song to sing (subtitled, "Jazz, you will love this")

[SpyNote]

Judging from the notes that are hard for her to hit on stage and how much the original versions differ from live renditions, I would say the following songs:

Dreams
Edge of Seventeen
Gypsy
Rhiannon
Silver Springs
Sisters of the Moon
Sorcerer

Of these, I would say Rhiannon is the most challenging to sing onstage.
