Rich,
First off I use a MacBook air for live performance BUT in a situation where I may need it, I have a set list on my Ipad and iphone
ready to go as backups.
On the iPad/phone I have an the app "Denon Audio", available in the app store.
On that app I have several set lists ready to go when needed.
It is a little more cumbersome to use than the BIAB on the computer but certainly an option for live performance.
Fortunately I have had to use it sparingly years ago before I had the Air. But rather than troubleshoot a computer
problem at a performance, it was easier to plug in the iPhone and continue the set using the Denon app.
