“Roy” of Johnny and Roy to Resuscitate “Trauma”?

From E!Online:

Kevin Tighe from Emergency! pops up in a couple of weeks. How did that come about?
It was just a phone call and that was pretty easy. The people of my generation and a little older are the only people who are going to get an Emergency! reference, but we had to do it! So many paramedics got into the field from watching Emergency!, so we knew from the first episode that we wanted to get Randy Mantooth or Kevin Tighe. Trauma is the great-grandson of Emergency! Granted we are a grandson with ADHD, but the DNA of that show and the DNA of our show are the same. There is a throughline, and we are really trying to head more in that direction.
