Sgt. Pepper's is often defined as a rock album but there are few rocks in it ... Getting Better is one example of the band making (soft) rock combining handclaps and harmonies like in their early times and albums ...
Getting Better it sounds somewhat as an Abbey Road LP track to me: 'clear' production and spice-alley guitars arrangements and harmonies tho drums are not in the vein of Abbey Road at all ...
P.S. Fixing A Hole's guitar reminds me of some of the Abbey Road LP tracks too ...
