Live comes at you pretty fast. Don't stop to look around once in awhile, you might miss it!
Back in 1993, an "oldies" station could play Elton John's "Crockodile Rock" (1973) and nobody would bat an eye.
Usher's music is now older than that!
One day you tune into KRTH, KOLA, or KQIE and hear something from when you were in high school. Despite my initial complaining that "KOLA is off the rails," I have to slowly admit that it's me who has gotten old.
