It's Pinky & the Killers - 60's, Japanese, stylish pop-in-bowlers. Fab.
This single was given to me by Dougee Dimensional and I've since tracked down a few more (including 2 in Japan recently). I also found a CD collection of their hits in the RECOfan in Shinjuku. They are all great.
I ask you, how could you not love this band?
