Old time rock and roll?

So, I came up with this quiz today to have some fun at the morning meeting at work today. Now, the majority of the people at the meeting were of the age group that could of known. So, the question that they had a hard time was "What song did George Harrison write and record and was sued for plagiarism?" Tick toc, Tick toc,Tick toc,Tick toc,.........MY SWEET LORD. He was accused by The Chiffons for copying the melody of their song "He's so Fine". And, who could not recall when John Lennon appeared for a whole week on The Mike Douglas Show??? Am I really getting old????? Someone please tell me........
