How do I delete a tag of an entire Facebook Album?

[anime addict]

So yesterday I went to Six Flags Frightfest and took many photos, when I got home, I uploaded them on Facebook, however, as it was 2 in the morning, and I was utterly exhausted, I had accidently tagged a friend who didn't attend, I didn't notice it until, this morning. It's a bit awkward considering he's only an acquaintance. Please help.

Click on the album. Press edit. You should see the album contributor's button. Delete your friend's tag.
