“I’m into Something Good” was made popular by Herman’s Hermits in 1964. The original version by Earl-Jean was also from 1964. The song was written by the husband and wife team Gerry Goffin and Carole King. Goffin got Earl-Jean pregnant!
from Wikipedia: Carole King has said that in writing the song she was inspired by Brian Wilson: “I make no bones about it, that song was influenced by Brian’s music”.[5]
