Great, thanks guys, sounds like this may save me some $!
It occurred to me after I posted this that my mixer (A&H CQ18T) can be used as a USB interface; I will set it up and try it with my iPad and stage tracks. If that works it would be perfect, no need for additional hardware other than a USB C to B cable! (maybe a special one with an extra port for charging tho...) I did see a youtube vid of a guy doing this very thing with his behringer X18, so hopefully the A&H supports this too.
Great to hear that works Sharonzaz. I will probably end up with a similar setup. Also, nice job staying in tune with that lady singing off key :-D
