Valli scored 29 Top 40 hits with The 4 Seasons, one Top 40 hit under The 4 Seasons' alias 'The Wonder Who?', and nine Top 40 hits as a solo artist. As a member of The 4 Seasons, Valli's number one hits included "Sherry", "Big Girls Don't Cry", "Walk Like a Man", "Rag Doll" and "December 1963 (Oh, What A Night)". As a solo artist, Valli scored #1 hits with the songs "My Eyes Adored You" and "Grease". Valli's recording of the song "Can't Take My Eyes off You" reached #2 in 1967. "You're Ready Now," a Valli solo recording from 1966, became a surprise hit in Great Britain, as part of the Northern soul scene and hit number 11 on the British pop charts in December 1970.
