Jugband blues (Pink Floyd)

It's awfully considerate of you to think of me here And I'm most obliged to you for making it clear That I'm not here. And I never knew the moon could be so big And I never knew the moon could be so blue And I'm grateful that you threw away my old shoes And brought me here instead dressed in red And I'm wondering who could be writing this song. I don't care if the sun don't shine And I don't care if nothing is mine And I don't care if I'm nervous with you I'll do my loving in the winter. And the sea isn't green And I love the queen And what exactly is a dream? And what exactly is a joke?
