Step 1 : Introduction to the question "What musical group claimed "You're gonna need an ocean of Calamine Lotion" in a 1959 song?"
...One of the few groups in rock history to successfully walk the line between music and comedy began as a doo wop group called the Robins out of Los Angeles. The group morphed into the Coasters by the time their first single, "Down in Mexico," hit the Top Ten on the R&B chart in 1956. Their first number-one pop hit came in the summer of 1958 with "Yakety Yak," followed by "Charlie Brown." They continued to build up the hits with their Western-themed "Along Came Jones" and their shout-out to Calamine Lotion in "Poison Ivy." Source: AllMusic.com
