So, there are various stories about the original of "4-20" being code for getting high, but I'll go with the bunch of high school kids who used to meet under the football bleachers after school at 4:20 every afternoon to get high.

1) "SGT. PEPPER/WITH A LITTLE HELP FROM MY FRIENDS" - BEATLES ("I get HIGH with a little help from my friends...")
2) "HOT BLOODED" - FOREIGNER ("I'm a little bit HIGH")
3) "ROCKY MOUNTAIN WAY" - JOE WALSH ("Couldn't get much HIGHER")
