Get ready to have your minds blown: Did you know that Celine Dion did not, in fact, originate the song “All by Myself”? That honor belongs to Eric Carmen, a singer-songwriter from the seventies, who apparently got into quite a bit of trouble with the Rachmaninoff estate in the process. Dion, of course, gave it its diva panache, and without her, it certainly would not have landed such a prominent role in last night’s episode of Glee, which, no matter what you thought of it, featured a rousing (if random) performance by power-belter Sunshine Corazon, a.k.a. Charice, the Filipina pop star. Other noteworthy performances throughout history include: Rhap Salazar, Charice’s fellow Filipino, and Pia Toscano, who is a victim of neglect indeed.
