My, my, hey hey: The hottest S.F. concert ticket this December might just be a benefit concert for the new UCSF Benioff Children's Hospital.

The headliner: A Canada-born, now-local folk-rock singer (who's had some car trouble lately) by the name of Neil Young.

The opener: A freaky California-born folk songstress (who may have recently released her magnum opus) by the name of Joanna Newsom.

The price: Will make your eyeballs pop out of your head when you see it after the jump — but it goes for a good cause.
