I am handicapped (no wheel chair) but qualify for tickets in the first few rows. Where do I get a handicapped ticket? Can I have a person sitting with me?

I think ticket master has a disability icon when looking for a seats. Red rocks does have an app with upcoming events. My dad was in the same boat as you, generally one or two people got to sit with him depending on space each venue was different. Hope my answers was helpful have a nice day ✌

I can't answer your question regarding tickets, but I've attended concerts with my disabled family members. We were allowed to sit in the handicapped section. Mind we were a party of two and no wheelchair. You can also check with your library. They have discounted tickets for the disabled with a plethora of available outings.
