This Saturday's show (3.24) is my last one before our spring membership drive begins. I want to make it an especially good one, so I'm doing a Common Thread Saturday. Here's how it works: I'll play three songs in a row. All three of them will have something in common, a shared element or common thread that links them. When I start the third song, if you can identify the common thread, call me at 314.664.3688 and we'll talk on the air. It should be fun.
