5 Seconds of Summer Radio

Now that fall is finally here, so are #FallSongs. Jimmy Fallon had 5 Seconds of Summer on "The Tonight Show" this week to help sing new fall lyrics tweeted in by fans.

For each song, fall words replaced some of the song lyrics. Blink-182's "All The Small Things" became "All The Fall Things," and Jay Z's "99 Problems" became "Halloween Problems."

Get that pumpkin spice latte ready and check it out below!
