I'm guessing then that the sunburst 70s Strat was used on the Lulu Show while Sam Li was working on the white one which was certainly resprayed by the time of Eurovision.
Stuart: yes, the use of the ex-Tony Hicks Strat on Memory does ring a bell. I remember an interview in Guitarist where Tony expressed his amusement at selling a Strat to Hank.
If my memory serves me right, the all-red Fender lineup was in place by the time of the XXV tour, with what appeared to be a set of sunburst models on stage as backup, though I'm guessing that Hank's was the ex-Hicks one.
