What business did Paul McCartney
once describe as "western communism" ?

The recording industry???

Nope ! This a specific enterprise
which he and his mates had a piece of !

Bsed on the last clue, my only guess would be "Apple Records."

Close enough, actually
Apple Boutique specifically !

Thanks for the answer Yankees15 !

My sister and I went to school just around the corner from the Apple Boutique and walked past it every day,it was originally painted with a huge psychedelic mural,but it had to be whitewashed over as the local residents complained,we thought it was fantastic, especially as we would occasionally get a glimpse of John Lennon in his white rolls royce.
I would love to see a picture of the shop before the murals were painted over,does anyone know where I could find one ?

Apple (#3)

Thanks dog, they're great.
Boy do they bring back memories,that's the first time i've seen it since it was painted over,I was only about 8 years old but I remember it vividly.
