There's no shame in diggin' on a little Starland Vocal Band or some Supertramp. Don't feel bad if you truly love Judy Collins. There's a place for you where people understand. That place is in Mesquite and it's a radio station with high school kids for DJs who probably have no idea whom they're playing. We'll give them the benefit of the doubt because they crank out the '70s Top 40 as if wool dickeys and macramé owls were back in style. With Robert Bass in the music director's chair, the station offers all the best from the age of super-sappy love songs. Jim Croce and Ambrosia never had it so good, even back before they had songs on albums that weren't Time/Life collections.
