While attending Ealing Art College, Tim Staffell became friends with Farrokh Bulsara, a fellow student who had assumed the English name of Freddie. Bulsara felt that he and the band had the same tastes and soon became a keen fan of Smile. In late 1970, after Staffell left to join the band Humpy Bong, the remaining Smile members, encouraged by Bulsara, changed their name to "Queen" and continued working together. When asked about the name, Bulsara explained, "I thought up the name Queen. It's just a name, but it's very regal obviously, and it sounds splendid. It's a strong name, very universal and immediate. It had a lot of visual potential and was open to all sorts of interpretations. I was certainly aware of gay connotations, but that was just one facet of it."

Tim Staffell left the band Smile in what year?
