The Ideal:
Storms acoustic with Lindsey playing guitar, complete with closed eyed Lindsey, and gazing Stevie, etc. SIgh.
Angel straight out of the Tusk video, complete with bouncing (ahem) around and such.
Sisters of the Moon with the "ignorrrrrr our own voice" and "i won't be like your sistah, like yer brotha, like your sister)#(#)($* )#(%* #)(*#)(*$#) at the end with her hair all over the place like the Mirage take.
Basically any emotional, powerful punchingthehelloutofyougowithyourbadself version would be just fine by me!
