Answer the question at the end by quoting:

Robert Stanley Crewe (November 12, 1930 - September 11, 2014) was an American songwriter, dancer, singer, manager, and record producer. He was known for producing, and co-writing with Bob Gaudio, a string of Top 10 singles for the Four Seasons. As a songwriter, his most successful songs include "Silhouettes" (co-written with Frank Slay); "Big Girls Don't Cry", "Walk Like a Man", "Rag Doll", "Silence Is Golden", "The Sun Ain't Gonna Shine (Anymore)",
In 1953, Crewe met and partnered professionally with Frank Slay Jr., a young pianist from Texas. Their collaboration created several hit songs (as well as a small record label, XYZ), for which Crewe performed as the demo singer. Crewe and Slay's 1957 recording session with the Rays for XYZ (picked up nationally by Cameo Records) produced two major hit songs. "Silhouettes", produced by Crewe, became a doo-wop anthem of the era. Climbing to #3 on the Billboard Hot 100 in 1957, "Silhouettes" displayed the flair for story-driven lyrics, innovative musical hooks, and final lyrical twists that were to become known as Crewe trademarks. In 1965, with a slightly faster tempo, "Silhouettes" again became a hit, this time for the British group Herman's Hermits, reaching #5 on the Billboard Hot 100. Bob Dylan recorded "Silhouettes" during his legendary Basement Tapes sessions of the late 1960s, although his version was not released until 2014.  "Daddy Cool" was the B-side of the Rays' "Silhouettes" single. Written and produced by Crewe and Slay at the same 1957 session, it achieved considerable note. Both "Daddy Cool" and "Silhouettes" were covered the same year by the Canadian group the Diamonds, whose version of "Daddy Cool" reached #10 on the Billboard charts. In 1961, Guy "Daddy Cool" Darrell released another single version on the Warwick label, and in 1977, the UK band Darts made the song their first-ever studio recording, scoring a #6 hit.  Crewe and Slay built on their success by signing a deal with new, Philadelphia-based Swan Records. Sessions with Billy and Lillie (singers Billy Ford and Lillie Bryant) produced the 1958 hit "Lah Dee Dah", which reached the #9 position on the Billboard Hot 100; the following year, Billy and Lillie's recording of "Lucky Ladybug" hit #14. Crewe and Slay also wrote two Top 10 hits - "Tallahassee Lassie" and "Okefenokee" - for Swan's rising star Freddy Cannon.

was their anything significant about Bob Crewe in 1950s?

Their collaboration created several hit songs (as well as a small record label, XYZ), for which Crewe performed as the demo singer.
