In short: It Won´t Take Long is just the kind of - positively said -
simplistic formula which hang much on the player & singer of the song.
It make me think of BS and 1971 and the time around LIB, SF & EOMS (+ER,TY).
I think we will do lots of associations the following weeks and a year
from now on, associations to the period circa 1969-1973 plus 1978-82.
