"So if you're still listening after all that, here's this week's story ..."
My suggestion:blah blah author bio blah blah and then, no transition, just a very brief pause..."I believe in (oblique reference to story). In a few minutes, so will you."ie:Osteomancer's Son: "I believe in the magic we feel in our bones. In a few minutes, so will you."Come Lady Death: "I believe death comes for us all. In a few minutes, so will you."(how's that for my intro/outro/editing audition.. )
