 I'm Casey Kasem on American Top 40. Our triathlon champs have swum through the 60s, cycled into the 70s, and sprinted into the 80s. Here's a marathoner who had his first hit, a number one song, back in 1963. Rolling Stone magazine said, quote, he has revered status, consistently creating daring, imaginative, widely heard, exciting American music for more than three decades. What's more remarkable is that he's achieved this status while still in his 30s.
