The first leg of my North American book tour for Under Pressure is over. My last interview here in San Francisco had a nice symmetry to it.Back in 1990, when I was in the final year of my undergraduate degree at Edinburgh University in Scotland, ABC’s Good Morning America came to town to do a few shows. I got taken on as a runner and ended up working with one of the presenters, Spencer Christian. We got along well and I’ve always remembered him fondly. So what a happy surprise to find Spencer waiting to interview me onView From the Bay.We even had a laugh about it on air. Sometimes TV can be a lot of fun…
