As if they weren't super enough. Delighting SM family fans everywhere, SNSD performed their SM sunbae Super Junior's, "Sorry Sorry" on Music Core. Though short of 4 members, the SM nonagon did the trademark shifty hands and wipe-dirt-off-your-shoes dance with flair, capping Music Core's summer special in style. Holy hexagons - SUITS. The performance was a bit shorter (Twojstary: shawter?) than some would've liked, but I don't know if my nervous system could handle 3+ minutes of that. If you need something to calm you a bit, here's something we're more familiar with - a classic Music Core performance of "Tell Me Your Wish (Genie)" Kudos to soshified.com for top banner and prot0980 for videos.
