Alvin Lee, guitarist for...

...the British blues-rock band Ten Years After, died at age 68. From his obit in the Times (my emphasis):

Ten Years After attracted a following during its first tour of the United States, in 1968, and the band would tour the country many more times through the early ’70s, known less for hit songs than for extended jams.

“The strange thing was we had gone to what I considered to be the home of the blues, but they’d never heard of most of them, and I couldn’t believe it — ‘Big Bill who?’ ” Mr. Lee recalled in a 2003 interview with Classic Rock magazine. “We were recycling American music and they were calling it the English sound.”

As for the above song:

  

Then, during a break in 1971 intended to provide time for musical exploration, Mr. Lee wrote the band’s only Top 40 hit, “I’d Love to Change the World.” The song’s more commercial sound was a departure, and Mr. Lee later said he was not sure it had been a wise one.

“I hated it because it was a hit,” he said in 2003. “By then I was rebelling, and I never played it live. To me it was a pop song.”
