I saw that you've been to all the shows I have, and at one of them, I'm fairly certain they played SPD. It was at the Palladium, I think. The last time they were there.
Well I went back and checked the set lists for all of those dates and I never saw it. It has been #1 on my wish list for a few years.
UPDATE: I checked the "How many times have you seen Opeth" thread, and Coma323 mentioned a show in Worcester on 09/19/08. I missed that show for one reason or another. This may have been when they played SPD.
