Of course, Tim Minear (or how ever you spell his name) worked on both those shows so that probably had something to do with it.
He wrote IGYUMS and was co-executive producer on Angel, so yeah, I think that's a safe bet.

There's two eps of Angel that are titled "I've Got You Under My Skin" and "That Old Gang of Mine".

I think I also read somewhere (but don't quote me on this) that the whole Connor arc in Angel was originally something planned for the 5th season of L&C with the Family Hour mystery baby.
