I voted squirrel.
But, ah... no.... to the Passengers question... if they can't get their shit together as U2 then I doubt adding Brian Eno or anyone else to the mix is going to solve their issues.
I voted for squirrel as well. There was a guy back in high school who used to say that, it was his thing. He had other little sayings that were offbeat and funny, odd even.
Don't know exactly what it means other than knowing the guys personality i have an idea what i think it means. Amazing that it has stuck with me all of those years.
OS1 is an absolute treasure. I bought OS1 when it originally came out, listened to it once part of the way through and put it aside since it was a bit out there for me. It sounded nothing like the Batman song or AB and Zooropa. My young mind wasn't quite able to comprehend this bizarre sounding music. Glad that i came around to it 20 years later or whatever.
While i do not think U2 retires and goes that direction, one can dream. I pretty much agree with what Soloyan has posted on the subject.
