Bennett's a social and political conservative in the US. He is not known for, nor was he hired for, his skills as a commentator or interviewer. FWIW, he's a Fox News regular and former Secretary of Education under Ronald Reagan. He does sometimes put his mouth in gear before engaging brain, as in this example from last year:
Addressing a caller's suggestion that the "lost revenue from the people who have been aborted in the last 30 years" would be enough to preserve Social Security's solvency, radio host and former Reagan administration Secretary of Education Bill Bennett dismissed such "far-reaching, extensive extrapolations" by declaring that if "you wanted to reduce crime ... if that were your sole purpose, you could abort every black baby in this country, and your crime rate would go down." Bennett conceded that aborting all African-American babies "would be an impossible, ridiculous, and morally reprehensible thing to do," then added again, "but the crime rate would go down."

Even the White House backed away from him on that one (publicly, at any rate.) Mr. Bennett has been called the Morality Czar and The Crown Prince of Cranky (my favorite) among others.
His enthusiasm for Gord's music merely confirms the universal appeal it has.
