Many other bands have shown one night only live concerts in theatres.
Phish
Prince
Bon Jovi
Queen & Paul Rogers

This is all true.

However you may be forgetting that Radiohead also did a similar thing. For free. Then they gave those videos to iTunes....for free.

It may not have been on a giant screen but far more people watched it than they would have had it been a theatre show.

Radiohead also did an IMAX show for HTTT, with comparable ticket prices to the Hip.

Well then. Was I living under a rock in 2004 or what?

Of course, Radiohead is now without a label, and a theatre show thing for HTTT would have been when they were still under EMI.
