Um, the Hosers were a TV thing. You needed the visuals for full effect.
I can't say I have heard of this Paul fellow, but it looks like he was big south of the border.
Do you have an AM radio?
Late at night, turn it on and start moving through the band. When you come across a man that sounds like your grandfather, talking about some nostalgic thing in a slow, reassuring, methodical voice, you've probably found Paul Harvey. And when he starts talking about Bose Wave Radios, Glucosamine/Chondroitin supplements, or SelectComfort beds in a manner that sounds like that same grandfather offering advice, you've definitely found him.
I didn't care for his style. But he was certainly a big name in the world of radio. He will be missed my tens of thousands of people. He was, more-or-less, a relic from the by-gone glory days of radio. And I mean that in a positive way.
