It actually looks like Greg might be leaving the Wiggles! How sad. Colin has loved them since he was teeny tiny, so I really hate to see this happen. Even though some of the music can be highly annoying and that laugh of Dorothy's can drive you up a wall...my kids love it all.
Thanks Greg, for all that you've done to make children all over the world smile, laugh, and dance!! I pray that your Doctors are able to diagnose whatever is happening with you, and restore you to full health and vigor as quickly as possible!!
You will be missed!
