Winifred, I should like to make a slight differentiation between the word cheerful and just plain giddy irresponsibility.
On a lighter note here are some happy videos I found and thought I'd share.
The first is a mix of Mary Poppins using samples from the movie with a bit of original music. My family sat around the PC this morning before work/ school and watched this a couple of times. Absolutely lovely.
This is a web ad for Cinematic Titanic so those of you who aren't familiar with what I was talking about can get an idea. I'm going to buy this one because it looks pretty funny.
This is an ad for Beatles Rock Band rolled out this week that is plain beautiful. Somebody should win an award for this damned thing. It's just that creative.
