Anyway, apparently they learned a new chant and they love it. They were wearig Guy and I out when they got home yesterday and started back up as soon as they woke up this morning. It's even stuck in my head now.
While I was cooking dinner tonight I got this video of them. Ignore the wardrobe they just got out of they bath :)
Don't forget to pause the music player at the bottom of the page so that you can hear them.
