I apologize if this has already been discussed but I didn't see it anywhere. And normally things like this are well-known to the Manson fanbase long before the actual appearance. But this kinda came out of nowhere. I was watching That Metal Show last night with guests Sammy Hagar and Michael Anthony, with John 5 as the guest guitarist.
And when they went to break, they showed a preview of next week's episode, and Manson is going to be on. Not as a featured guest being interviewed like he was in December, but as a special guest in the beginning of the show when the 3 hosts do their Top 5 list segment. John 5 is also guest guitarist for that episode and Manson spoke directly to John 5 as well, making him laugh. I didn't hear what was said because I was on the telephone, but I saw it and went apeshit. So look out for that next Saturday night on VH1 Classic :)
Anyone who catches a replay of the Sammy Hagar / Michael Anthony episode, watch out for that preview.
