The Avengers' huge final movie 'Endgame' came out this week, closing up the storylines of 20+ Marvel movies over the last decade into one big epic finale.
Because so much has happened across the many movies, it seemed fitting for the cast of 'Endgame' to recap the plotlines of every Marvel movie since 2008's 'Iron Man' to the tune of Billy Joel's 'We Didn't Start the Fire'.
Appearing on Jimmy Fallon's 'The Tonight Show', stars including Robert Downey Jr., Mark Ruffalo and Chris Hemsworth sing along to the famous tune - you can watch the video above.
Billy Joel himself famously commented that the melody was one of the worst he ever wrote, following him messing up the lyrics at a Toronto live performance in 2014:
"It’s the same thing verse after verse, just the words change — na na na, na na na, na na na na na na. One of the worst melodies I ever wrote. All you gotta do is fuck up one word in the song and it’s a train wreck."
