Similarish experience a couple days ago:

Was revising in the school library as I'm on study leave and was just going about my work quietly listening to music. Then a good song comes on and unawarely I start humming the tune and then start singing it but I did not realise I was doing it. So in the middle of the library filled with elder students everyone looks at me with a 'WTF' face whilst I'm singing and it was incredibly embarrassing.

I went bright red and just put my head down.

I feel for you Dezzy.
