I haven't really "gigged" live very much since the last band I was in crashed and burned. However, I was active in a church ministry that went to a prison once a month and I was responsible for the P&W music. I would simply create the tracks in BB and export them to my phone. This prison did allow us to carry our phones into the facility. Minimum security. The less we had to carry in the better off we were getting through the security checkpoint. A small PA and we were in business.

I'd recommend that you export your songs and use a laptop or some other kind of player that lets you access the songs quickly and in varying order as needed. Carry a backup player in case of crashes and other such glitches.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
