Oldies is a relative term. Which age group do you want to reach? Primarily male or female? I remember once calling Scott at Gold 104.5 to request a Doobies Brothers song from 1973 and he told me, with a bit of sarcasm, that the song was too "new" to play. He didn't agree but those were the programming rules.
I graduated from high school in '72, from college in '76. My brother graduated from high school in '77. Generally speaking, all oldies stations until now have been trying to reach the FIRST half of the baby-boom generation. No radio stations have attempted to reach the second half of the boomer generation with the music we listened to on WLS, Chicago, growing up in the Midwest. WKLU is playing the music that I listened to such as Earth, Wind & Fire, Carole King, Steely Dan, Jim Croce, Neil Diamond, Three Dog Night, Al Wilson, T Rex, etc.
WKLU's owner has great potential now to build an audience and to keep his sales department busy. Time will tell. Their signal has a lot of punch to it.
