I was wondering how far does the b stage go out into the crowd. like the old stages from the last 2 tours?

Very similar. It depends on how large the floor of the venue is.

70-204 feet. i.e. 20-60 meter. That is the offician figure. Distance from main stage to socaled satellite stage i.e. B-stage. During arena shows it is located 3/4 of the way from the main stage to the end of the floor, with few rows only on the floor in front of it. During baseball stadium shows it is sometimes on the diamond (inner field) like in San Diego, while other baseball venues they do not allow anything on the innerfield, so the main stage is placed with an angel, and the B-stage then ends up next and in front of the centerfield. There is a pictures in the latesr magazine IORR 53 which shows this very clearly. For the fooball stadiums it is usually 2/3 across the field. Some times Mick does actually walk all over during You Can't Always Get What You want! A long walk!

The stage go further out than the last 2 B stages. Its pretty cool to see it rise up off the main stage as the band plays on, to and from the B stage.
