Patti Labelle - Once Before I go. Simply wonderful and magic! When "Empress Of Soul" Patti Labelle begin held that note at 3m8s was so powerfull, with that fierce vibrato, so loud, that any other singer couldn't hit that note more than 5sec ... but Patti blooww for more than 20s and was so easy for her, Patti Labelle is a blessing
