Dave Grohl (center) and shoes (right) at the Ed Sullivan Theater

The next morning, I had to know if there was a story behind Grohl removing his shoes. So I reached out to a friend who used to work at RCA with the band. He forwarded my question to John Silva at their management company, who passed it along to Grohl.

Here’s the e-mail I got back!

Dude…….he’s right! It was!! remember the “Paul is dead” conspiracy? The shoes on the riser were part of it!! Apparently there’s red blood on the shoes!! Tell ‘em “good eye!” for me!!!
Ha!! I thought no one would notice!!

And yes, as Grohl mentioned, that was one of MANY “hints” at the time that [lastfm link_type="artist_info"]Paul McCartney [/lastfm]was dead!

If you haven’t already done so, take the time to watch the entire Foo Fighters Live on Letterman show — it’s a truly unforgettable and intense two-hour performance. And at the end of the show, you’ll see Grohl bring the shoes into the audience and give them to a lucky young fan!
