Larry King did this on every show and I’ve often found the audience questions are better! I’ve done this with every interview in every program for the past 30 years and I’m continually impressed by the questions that I had never even thought of. If you are the interviewee, be as honest as you can be. Start by asking their name (this makes it more personal) and then address their question with a ‘thank you’ and their name at the end. This is very useful on radio or live Podcast interviews…personal is always preferred over the anonymous voice.
