Well, Ira doesn’t view Garrison as his rival (He’s too big to be my rival). In this conversation Ira describes the differences between the two shows thus:
I mean, it’s interesting for me when I’ve gone to see Garrison Keillor’s show because it’s such a different kind of production than ours. His show, the backbone is really built around music. There’s music all the way through, and then he’s such a huge presence in the show in a way that is bigger than the presence I am in any or our shows. It’s his personality which really carries the show—and the fact that for most of it, he’s not working off of a script. He’s almost never working off of a script except for when they’re doing the radio dramas, and that’s kind of amazing to watch, too. That’s crazy when I see it. I could never do that.
On the other hand, Ira may feel very competitive with Garrison. Once he was very threatening, saying, “I will destroy both of them”, referring to David Sedaris and Garrison Keillor, both of whom would later visit the same venue. One hopes this is tongue-in-cheek, but…..?
Garrison has thrown his brickbats at Ira, too, as seen in this script from one of his shows. The story pokes gentle fun at Ira’s penchant for having really weird takes on subjects, and finding out semi-believable stuff about the people in the stories.
Many others like to compare the two. This Washington Post article says:
By the end of the first year, the show had been signed by 112 stations, and it rapidly became one of those rare public radio icons: a show all the stations want. And Glass found himself described in the same company as Garrison Keillor of “Prairie Home Companion” fame and NPR’s Terry Gross (“Fresh Air”).
I’d have to conclude that the two are respectful of each other, although I doubt if they are friends. They are at pains to say they don’t compete, but I wouldn’t be surprised if there is a little rivalry there. They clearly tease each other, but whether it is teasing born out of grudging respect, or teasing arising from a close friendship, who can know? My money is on the grudging respect cause, though.
Frenemies, I guess.
