Saw an ad for this in yesterdays NOTW (bought only for Tesco, of course!)
"Parents, if you're looking to introduce your children to a life-long love of music and singing, you've come to the right place!
Were passionate about getting all kids to enjoy singing as part of their everyday lives, so weve put together loads of fun stuff and activities to get your family started.
You don't have to be a primary school professional to stay up to date with Sing Up developments and offers. As long as you're in the UK you can register for regular email updates and, if you live in England, you can order the FREE interactive Summer CD ROM full of songs and music scores to help get children singing over the holidays."
Seems to be some sort of charity type initiative, so as always please only get one if you're really planning on using it with the kids!
There's also the option to download a load of weekly activities - anything free that'll keep 'em busy over the hols has to be a good thing!
