It’s fairly uncommon for locations to be named after anything other than the exact meaning of the name. If it isn’t the case, they are known for something else. Zebras have long been connected with London’s Abbey Road, although not because there are any zebras in the area. Just a name, something this person didn’t notice.
It’s possible that he was also unhappy that the Beatles were absent. That’s because it’s clear that he had high hopes.
