You Line, I Line, We All Scream For Uline: Years ago, the Uline Arena was the place the Beatles chose for their first U.S. concert; these days, it’s an empty husk of a building that’s barely visible except from passing Metro trains. It might soon be a music museum, though. Architects at HKS are convening a summit to come up with design ideas; if they find one that’s economically viable, the arena might one day come off the roster of vacant properties held by Douglas Development Corp. No word on whether Paul McCartney could be lured to play a set. +2

Wrath of Khan: Local boxer Lamont Peterson will have to beat Brit Amir Khan a second time if he wants to keep his belts. So says the World Boxing Association, which ordered a rematch of last year’s fight at the Convention Center because of “multiple irregularities” in the refereeing and scoring of the bout. No reason to worry, though; as long as the rematch is held in D.C., Peterson should be fine. Uh, because of the strong crowd support, of course. -1

Track Marks: Going somewhere this holiday weekend? Don’t be in a hurry. Metro has repair work planned for the Red, Orange, and Blue lines; virtually everyone who took the Red Line anywhere this week already knows how inconvenient single-tracking there can be. There won’t be any trains between L’Enfant Plaza and Eastern Market, which means any tourists hoping to check out the Capitol will be hoofing it. (Or taking Uber?) -2

Tie One On: Business casual is the order of the day for the men at most D.C. law firms (even if suits and/or blue blazers are still de rigeur on the Hill). Which may be why an attorney based at WilmerHale, David Powers, has teamed up with a buddy to start a business that rents neckties: Why buy ’em if you almost never have to wear one? For $29.99 a month, you get the use of five fancy ties. If this isn’t a sign the economy isn’t actually improving, we’re not sure what is. +1
