A hungover and a generally liverish feeling (why o why do I drink rum?) from a cracking evening at Sharp's yesterday.
Compounded by Doris bloody Day singing Que sera.
All together now...
Will I be bilious,
Will I be sick...?

It's one of those songs that turns itself into an earworm when I'm feeling below par, and it's insufferable saccharine jollity is driving me MAD at the moment!
