What’s Ummm Mean?

Lyrics

Love it occurs Way back in the back Furtive look Getting the book on one another As the eye opener And the fireman's fireman And the good old mayor of Paris And the mayor of Paris' brother Another looks At the peak from the last Tip of the cup The time isn't as of the essence as it once was The I think I know what I'm doing, do you? What do you think you're doing Or do you? Are you doubtless of where Your sun is grey Commanding Unspoken Till you're Septemberised Great Dismally real Come stay with me Stay And we'll wake and bake Though no one recommends it We'll feel A stay In our room Like innocents abroad We'll share the same face Till the day ends at When the sun is no better or worse It doesn't claim to Help it works There's always my colour, too And you can't hope for much The odd startling thing Do you suffer? Or have you ever suffered? What does umm mean?
