Granny Takes a Trip- The Purple Gang
A (fantasstic) classic 60's psych song that is actually named after a famous West London boutique. Granny Takes a Trip was one of the first boutiques offering vintage/"antique" clothing, which paved the way for other designer boutiques. Some pretty famous people shopped their too like Keith Richards, Rod Stewart, Syd Barrett. In 1967 the entire front of the store was a pop-art image of Jean Harlow, which you can see in the music video.
Anyways! There's a brief synopsis. (with the help of wikipedia)
