Yeah. I did: Riptide. I Need a Hero. I Dreamed a Dream. All-star. Be Prepared. Journey to the Past. I Bet My Life. Bittersweet Symphony. A fairly diverse list of songs that I mangled with my lack of voice control, but improvement is dependant on failure. The more epic, the better. That night, it was like someone had swapped my vocal cords for that of an Ibis with laryngitis.
Have you ever played Bioshock?
