Avid gym-goer Ramin Karimloo (along with Keala Settle, she wouldn’t leave after she shot her episode) was with Seth in studio for another go 'round of OBSESSED! Eight times a week, Karimloo handles the high notes of Les Miz's score with aplomb. Seth's theory — the highest notes are accompanied by lyrics that are easier on the voice, unlike the work of Andrew Lloyd Webber. Seth challenges Karimloo to some Cats, Sunset Boulevard and Phantom, replacing the original lyrics with some Les Miz for a bit less vocal stress. And Keala Settle doesn’t upstage or interlope at all. Nope. She's perfectly well behaved. Check out Seth’s weekly column. Visit SethTV.com, Seth’s online home.
