Originally written, recorded, and released by Eric Carmen in 1975, “All By Myself” has been covered by many artists, perhaps most notably Céline Dion. The verse of the tune is based on the second movement of Sergi Rachmaninov‘s Piano Concerto No. 2 in C minor. While Carmen’s original did not include a key change, most contemporary covers, including the 2007 version featured here by the pop male vocal group Il Divo, do (you can find it at 3:12.)
