If you haven't discovered this website, you need to. Jon "Rock and Roll" Anthony, who was on several different Birmingham stations during the 70's and 80's, has a website mainly devoted to airchecks from 70's and 80's Top 40 stations. Every week he posts a new clip that's truly a blast from the past. The newest installation in the series is a 1976 clip from WSGN featuring nighttime jock Chuck McCartney. Other recent posts include clips of Amaysa Kincaid (WSGN), Jim Christian (96-ERC) and Reid Lundy (also from WSGN). The 'SGN clips are particularly timely, since 4/26 will be the 26th anniversary of the end of what many people consider the greatest radio station in Alabama history (or at least Birmingham history).
