Interesting answers. My immediate thoughts went to lyrics less deliberately obscure (I mean you kind of expect twaddle from ELP, King Crimson, etc). One obviously thinks of such tracks as 'Bohemian Rhapsody' and 'Stairway to Heaven' as having that pretence of profundity but being merely the emperor's backside.
The songs I first thought of where 'Walking on The Moon' (for the surreal line 'I hope my leg don't break') and ALL of 'I Don't Like Mondays' (or is it 'Not Keen on Sundays'? or maybe 'Never Been Particularly Fond of Wednesday Morning'? or perhaps 'Thursday Afternoons Piss Me Off'? .... anyway). That one gets me because Sir Bob STILL thinks it's a classic. Which it is.... classic tripe.
I do like the nomination of the entire Howard Jones collections though. Good call.
