Happy Days - Seasons 1 and 2 of the series used a newly recorded version of "Rock Around the Clock" by Bill Haley & His Comets (recorded in 1973). The original 1954 recording returned to the American Billboard charts in 1974 as a result of its use on the show. The "Happy Days" recording had its first commercial release in 2005. (When Happy Days entered syndication in 1979, the series was retitled Happy Days Again and used an edited version of the 1954 recording instead of the 1973 version).
The show happy days aired in mid 1970's was based on family life during the 1950's. This show was all centering around respect. Respect for family, self, girls and much more. Considering the 50's was all about respect, the show Happy Days was a perfect example through pop culture of how this value was shown.
