Pink Floyd - Arnold Layne Lyrics Meaning

I was the inspiration for the lyrics! Was a student at Cambridge in 1966, living in Rock Road where Roger's Mum was my landlady. One early summer Sunday morning, when all the guys were hanging out round the kitchen table, I went out to bring in my washing from the line... lots of T shirts, jeans etc, but also lots of gaps where my knickers and bras had been hung up! I was livid but the fellas found it highly amusing... nine months later, Arnold Layne was released. Never found out if anyone had been "done" for it.
