The Sounds Of Summer- Day 46 out of 95- “Good Day Sunshine” The Beatles . As summer nears its mid point- it finally seems like at least in these parts- there has been a break from a lot of rainy days- and the sun has been out for a week. The Beatles “Good Day Sunshine” is credited as a Lennon-McCartney song- like all of John or Paul’s songs were but this is a Paul McCartney song all the way. I can’t imagine John writing it. “Good Day Sunshine” was the opener on side 2 of The Beatles greatest album “Revolver.” The summer of ’66 in England is remembered for England winning the World Cup- but it was also an unusually hot and sunny summer in England.
