I taped the play when it was originally screened in 1982(?). As far as I know it hasn't been screened since. I had a Betamax machine and was able to transfer it to VHS just before this machine died. The quality isn't very good, though I figured anything is better than nothing.
Don't know what the protocol is, though I could burn it on to a DVD for you, if you want to cover the cost of the disk and postage.
