For the last few tours, Alex Lifeson–the guitarist for Rush–had a Mr. Potato Head on his amp.

For this tour, it looks like he’s got a bunch of Barbie Doll groupies (as well as Mr. Potato Head) all holding up little stickie notes. Apparently, the stickies are changed each show by the roadies. They include notes such as:

“I like the drummer” and
“My grandpa thinks you’re cool” and
“I was conceived at a Rush concert”

among others.
