A bit more on 'the Duck', here's some info of how well it did in Australia:
'Aussies were always fond of a guitar-based instrumental. The Shadows were as big here as they were in the UK, and they were still charting alongside the Beatles into the mid-60s: their last hit in Oz was Bombay Duck in 1967 (#3 Adelaide, #10 Brisbane). The Americans preferred The Ventures, but we liked them as well: best of both worlds, down here. When surf music came along we took to it in a big way, and it melded in nicely with the guitar instrumental genre.'
That came from: http://poparchivesblog.blogspot.com/200 ... nder.htmlm: , of course they overlook the return of the reformed 'Shadows' in the 1980's.
