I thought he was just going to sing "Instant Karma"

Perhaps you have heard about the "seance" held with John Lennon recently on pay-per-view television. My disclaimer right from the get-go is that I don't buy into this stuff. The reason is pretty simple. Among them, whenever I have seen/heard these things, they usually with another person. I've heard that the best of these are really very skilled at reading subtle messages given by the living interviewee. So one of these usually ends up like this:

Madame Wienerschnitzel: Do you own a house?
Unsuspecting Customer: Why, yes, I do!
Madame Wienerschnitzel: Udish, your Mesopotamian ancestor, told me so.
[now makes careful judgments about consequence of owning a house]
Madame Wienerschnitzel: Udish also says your house...has a front door?
Unsuspecting Customer: [brief pause]...yeah, I think it does!
Madame Wienerschnitzel: He also says...now this is interesting, that your social security number has nine digits?
Unsuspecting Doofus: Yeah! It's [removed from transcript]!
Madame Wienerschnitzel: He finally says to not check your credit report for a few years.

Anyway, I believe it took quite an effort to come up with something John Lennon might say...and sure enough, it was.
