Coming in at #18(up 4) on this day in 1973 was the third top 10 hit for Irishman Gilbert O'Sullivan, who was known for his college sweater fashion sense. This peaked at #7 and is probably the least-played of his top 10 hits. I remember hearing this all of the time back then and now it proudly takes residence in The Retro Attic rotation!
A chart side note: also on this day in '73, Maureen McGovern raced up 11 spots to #9 with "The Morning After" from the classic film "The Poseidon Adventure." It would soon hit #1, and I remember Casey Kasem not liking it too much when it got there. At that time, American Top 40 was predicting what would be #1 the following week, and Casey made a quick and confident prediction that she would be knocked off the top. He was right! It's all good though; I would rather listen to a Maureen McGovern hits collection than a bunch of so-called LMFAO classics!
