A word here about all the traveling: It’s very complicated, and for the purposes of the official schedule, there was a personnel code which listed us under our Code Numbers rather than our names–making scheduling easier. Micky was given number 1, Peter had number 2, Mike had number 3, Davy had number 4, and I had number 10.
