Well,
It was Hitchhikers Guide to the Galaxy which was the real winner. It was the original radio version on audio book. I was surprised but the kids totally got it and have been trotting out quotes ever since.
Queen was tried out, and apart from enlightening me a bit, was met with indifference. Slaves was also enjoyed, though not by my other half.
Lots of infinite monkey cage/desert island discs too, when the boys where lost to minecraft.
