[1st verse:] Did you hear it? Were you near it? If you weren't then you've yet to fear it Once you've met it you'll regret it Just because you never will forget it If you ever wake up from your dreaming A-scheming, eyes gleaming Then if suddenly you take a screaming fit That's it! [Refrain:] That mysterious ra-ag While awake or while you're a-slumbering You're saying, keep playing That mysterious dra-ag Are you listenin'? Are you listenin'? Look! Look! You're whistlin' That mysterious ra-ag Sneaky, freaky ever melodious, mysterious rag [2nd verse:] Any minute they begin it E'er you know what you're about, you're in it Then a feeling, most appealing Comes a-stealing, sets your brain a-reeling When it's too late and ev'ryone is yawning Good morning, day dawning Then if suddenly you hear a warning shout Look out!
