The French word 
égale is a noun meaning "equal." The adjectival form of the word is 
égal, which can also mean "even; level" when referring to a surface. A useful phrase to know is 
Ça m'est égal. It means "I don't care." 

The lyrics of 
In The Summertime are pretty tame compared to the sex-and-violence themes of so many 1990s-2000s rap songs. Here is a sample:
"When the weather's fine
You got women, you got women on your mind
Have a drink, have a drive
Go out and see what you can find...
When the winter's here, yeah, it's party time
Bring your bottle, wear your bright clothes..."
Yes, fairly tame.....although the admonition to drink and drive certainly didn't show any wisdom!
