Ray Benson from Asleep at the Wheel says Mack also helped his group in the 70s.

“Most DJs just play music but this guy wrote incredible songs,” Benson said.

DFW radio host and former co-worker Mark Davis says he marveled at how popular Mack was despite the late hour he was on the air.

“From the years Bill broadcast in that building at 3 o’clock in the morning you could find 18 wheelers parked in our empty parking lot, the front door swinging wide open so that listeners, truckers, whoever might wander in and have a word with Bill, that’s a sign of a different age, that’s a sign of a different kind of radio guy,” Davis said.

He was an amazing father, grandfather, great grandfather and husband to my mom. I’m blessed to have had not only a great dad but my best friend as well.”
