Elvis had been lucky with #1 hits. He had number 1 singles every year between 1956 and 1962. But Good Luck Charm was the the last one he would have for awhile. He had a lot more charted songs, but not another #1 on the Hot 100 until 1969.

Fools rush in where wise men never go.
But wise men never fall in love, so how are they to know?
