LOL... I actually was caught about two weeks ago... singing "I really like you baby" by Melissa Etheridge, two guys from the local club whizzed up beside me and paused for a moment to chat - I felt a tad embarrased... but they gave me a tow for about 6km before they turned off my road, so maybe my singing wasn't too terrible.

I tried to phase this guy in my grade a couple of races back - he had annoyed me the week before by sucking my wheel the whole race and then trying to sprint me for the finish - but I outsprinted him .... ha!
So I tried to phase him in the next race by leading him up a hill, and singing another Melissa song - "Come to my window" - as I neared the top, then powering away once i reached the top (powering away being a relative term - remembering I am in the slowest grade in the club).

Singing out loud or in my head is a great way to keep a rythym - I often do it.
