British Invasion Rock n' Roll

Just to clear up any confusion I'll list some bands I consider to fall under the category of British Invasion rock. The Beatles, The Rolling Stones, The Clash, The Kinks, The Who, Pink Floyd, Herman's Hermits, The Animals, The Yardbirds, the Troggs, Etc...
(P.S. top picture: The Who, bottom piture: The Beatles)

My Plan of Action

My plan to find all this information on my research topic: "British Slang: Music" is to use the internet to find articles describing British slang, to interview my classmates if they think "British Invasion" music as slang being used in it, and finally to listen to the music and look up lyrics to see if there is evident slang being used.

My Questions

- What are the characteristics of British slang?
- Do some artists/bands use more slang then others?
- Is there a difference between British slang and popular American slang?
- Does slang give British Rock its unique characteristics, or is it something else?
