Poisson Rouge is a very decent website with games (in French and English) for kids - or indeed, hungover adults.
We've also just been given a CD called Sing Along with Putumayo which includes a funk-blues version of "Old Macdonald Had A Farm", and lists the wonderful Arlo Guthrie among its performers. It's the only thing we've come across so far (though I've no doubt there's lots and lots of good stuff out there, if only you know where to look) in English which rivals Henri Des, a popular French composer and performer of children's songs who gives live concerts. I can't think of an equivalent for him in English - musically accomplished and genuinely entertaining for all ages - other than the Muppets, who are as old as I am.
Anyway, feel free to check 'em out or pass 'em on with my recommendations and compliments.
