Frank Sinatra

Call me irresponsible - call me unreliable, throw in undependable too
Do my foolish alibis bore you, well I'm not too clever - I just adore you
Call me unpredictable - tell me I'm impractical, rainbows I'm inclined to pursue
Call me irresponsible - yes I'm unreliable,
But it's undeniably true - I'm irresponsibly mad for you
