Well, Arlo uses the initials ADG at his Website, but it's not something that's published often in other places. Therefore, it would make me think that it's a good possibility that the guest is Arlo himself - or perhaps an Arlonet regular. Since there is no mention of illness on Arlonet, it seems quite certain the rumor is false.
I think it's in our interest to be very careful about posting information that could turn out to be rumor. We've seen some of them here, expecially with virus hoaxes, and we've seen how people can get in a tizzy about something that turns out to be untrue.
Nope, we can't prove that Guest ADG is Arlo, but it seems reasonable. He's one performer who doesn't seem to be afraid to make his presence known on the Internet. He's has e-mailed me answers to a couple of questions, and was very nice about it.
