The big news on the talk show circuit this week is Paul McCartney’s Wednesday night guest spot on “Late Show with David Letterman.” The appearance is not only Macca’s first time on Dave’s show, but it also marks a return to his roots. The Ed Sullivan Theatre, where Letterman’s show is taped, was where The Beatles made their American debut on “The Ed Sullivan Show” 45 years ago.

For pure curiosity value though, it’s hard to beat a scheduled appearance by Twisted Sister on “Live with Regis and Kelly” Wednesday morning. Talk about your fish out of water. Things could get interesting.
