What do you sing while cycling?

Annie's Song by John Denver. No idea why, but ever since I started cycling it's the song that always gets deep into the head and stays forever.

I've done Double and Quintuple Ironman with that song on a maddening constant brainloop. Screaming it at the top of my voice in the middle of the night improvising new words to keep from falling asleep or flipping out. It messes with the old sanity.

That's a depressing song.

How about 'Grandma's bed' instead.....

'It was nine feet wide, six feet high, soft as a downey chick'
