I've got my whistle out!
I adore Odyssey too. Quality singles all of them. Amazing this was their first to chart since Native New Yorker at the beginning of 1978, and went all the way.
Gatherer, I must admit that today's 1980 chart has been one of the most blatant examples of what some on here have been complaining about, I will admit that entirely.
Plus, FOUR cover versions, Darts, Leo Sayer, Don McClean & Detroit Spinners in place of original 1980 release singles.
Xanadu is one of the earliest tracks I recall first hand hearing Tony play on Radio 1 on my first ever radio, a Harrier Pilot!
