Just saw it on the last set of adverts and apart from bringing back memories of clackers and bikes (:0)) and family camping trips and the great sound track (love that song) I actually struggled to place it as an ad for Halfords right until the end when it said what it was for.
Had to watch it a couple of times to get it but it's really nice. The way I see it, the couple camping are playing with their younger selves (or memories).
