At one level, this is a charmingly silly video which makes use of a copyrighted song, owned by Sony. Until now it would have been subjected to a takedown notice. But notice the “Buy song” button. Apparently it has propelled the track into the charts again. Could this be an indication that Sony has finally begin to understand the value of surfing a wave rather than doing its own celebrated imitation of King Canute?

LATER: Neil MacNeil sent me a link to this post, which details the beneficial impact of Sony’s decision.
