How Can You Be in Two Places at Once When You’re Not Anywhere at All is a 1969 comedy album by the Firesign Theatre. It’s certainly my favorite comedy record. The two sides have some cross-references but are very different.
Side 1 is “How Can You Be in Two Places at Once When You’re Not Anywhere at All”, an imaginative tale that starts with the purchase of a car.
Side 2 is “The Further Adventures of Nick Danger”, a parody of 1940s radio crime stories.
There are lots of cultural references to things like the Beatles and drugs. I think it wouldn’t mean as much to people who didn’t live through this era.
