Gypsy, I understand your feeling but you also have to understand that the essence of theatre is that it is live and ephemeral. There are many things I would love to have been present for, but that's not how it works. You have to feel good that most of those people who DID see those original productions you covet willnever see the many shows originating now that you do have a chance of seeing.
I do not have a moral issue with copyrights, but I do have a moral issue with invading the privacy of people who perform in shows not intending that they be preserved for my entertainment. In that sense, watching a bootleg is a form of voyeurism, not unlike wishing you could see your hot next door neighbor taking a shower but knowing that punching a peephole in the bathroom wall is wrong.
And Wilmingtom, yes you can watch those films under false pretenses with little chance of being called on it unless you do something extreme-just like you can cheat on your income taxes and get away with it more often than not.
