Dear Screen-Lers,
  On behalf of a colleague-to-be, I'd like to purchase a video copy
of a performance of Humperdinck's opera _Hansel and Gretel_.  Format
doesn't matter, since the dept. in question can convert from US to
PAL or vice versa.
  Any suggestions on where I could locate a copy in the next 2-3 weeks?
  Thanks.  I know this is the sort of info that appears regularly, but
of course one never pays attention to the specifics until it applies
to oneself.
[log in to unmask] or via Screen-L (either preferable
  to simply replying--thanks)
