who is the original singer of all by myself
All by Myself "All by Myself" is a song by American artist Eric Carmen released in 1975. The verse is based on the second movement (Adagio sostenuto) of Sergei Rachmaninoff's Piano Concerto No. 2 in C minor, Opus 18. The chorus is borrowed from the song "Let's Pretend", which Carmen wrote and recorded with the Raspberries in 1972.[5]
