OK Mendelssohn

Recently I started listening to the local classical station, WCRB, for no particular reason other than a change of pace from the MIT station, WMBR, where I usually keep my nightstand clock-radio parked. (Well, I suppose it's also because I've been reading Gödel, Escher, Bach and wishing it had come with a soundtrack CD.) Anyway, last night I heard Mendelssohn's Hebrides Overture and a melody from it sounded familiar. Watch it on YouTube and see if you also recognize it: it first comes in at the 2:18 mark.

( No really, go watch that before reading further... )
