(Well not really, but I couldn't pass up the chance.)

Extremely local DC version:

Bailey's Crossroads
Seven Corners

I can understand their conflatability, but they are adjacent to one another, mushing into one area at points.

A Maryland equivalent is the Bethesda-White Flint-Rockville axis.

Woe betide the person who gets mixed up on Bethesda vs. Chevy Chase vs. Silver Spring, because those really are in very different places.

I always get W.A.S.P. mixed up with Ted Cruz’s old band band Stryper.

For kinda obvious reasons.

i mean i think i've just never bothered to distinguish them, i was going to make a joek abt the star child in 2001 and the freaky udo-baby in the kingdom but it very much depends on them being one person not two

It Ain't Me Babe
I Got You Babe

The latter was a conscious re-write (rip-off) of the former!

That would make sense. I just realized this morning that I'd been skipping over the Turtles' cover of Dylan's song because I assumed it was the Sonny & Cher one.

OMG

Unlike my other contributions to this thread, this pair (who will mean nothing to people outside the British Isles) have actually lived in my head as the same person, said head troubled only by the fact that they seem to have two very different faces. I'd put this down to one being a jokey avatar on social media that I didn't get.

In the mid 80s I was just learning about the world and the people in it, and was very confused about why two of the most famous people had almost the same name, even though they were completely different people.

Madonna
Maradona

Managed to remember which was which by the age of 8, so all worked out fine.

The Asphalt Jungle
Blackboard Jungle

Wet Leg
Dry Cleaning

Not sure why exactly, but on seeing them both appear on the same end of year list I've realized that I mentally classified these two names as being the same band. Now I'm not sure if I've actually heard both of them.
