A couple of years ago, I was asked if I could do a "tape-sync" in Paris for Scott Simon, the host of NPR's Weekend Edition Saturday. A tape-sync is nothing glamorous; you just hold the microphone in front of the guest while the interviewer asks questions over the telephone. I was to send the good quality recorded sound to Washington, so the conversation wouldn't sound like a "phoner," as we call it.
Usually, with my own busy schedule, I don't have time to do tape-syncs. But I made time for this one because Scott Simon's interview was with Omar Sharif!
