How much time between Pretenders and Stevie?

[twinmatrix]

Sorry if this has been asked before! I LOVE the Pretenders and don't want to go to the bathroom during their gig. How much time is there between TP and Destination Unknown aka Stevie?

I'll be front row if that helps.
Also -- does the front row move to the center (in other words, away from their official seats) of the stage, and stay there? Does that mean "losing your place" by taking a bathroom break in between?

Just want to make sure I'm prepared haha.
