The wait is over — the awesome musical crossover episode between The Flash and Supergirl has finally aired, and it was just as toe-tappingly good as we all hoped it would be. Finally adding a cheery tone to 's otherwise plodding Sesaon 3, "Duet" was a tonic for the show's ills, even healing the relationship between Barry and Iris as the Scarlet Speedster learned an important lesson about love. (I guess Kara also learned something about love, but considering it was a stupid-ass lesson about forgiving asshole behavior, I'm electing to ignore it).

The tie-ins to didn't seem forced at all, and although it wasn't a musical number, one of the highlights of the episode was seeing Kid Flash, Vibe and Martian Manhunter work together to capture Darren Criss' Music Meister — proving once again that the backup-singer superheroes are just as interesting as the spotlight speedster, and it would be great to see them share the limelight more often.

Now the curtain has fallen, and we've all given "Duet" the standing ovation it deserves, let's count out all the fantastic Easter Eggs and musical references we spotted in Season 3 Episode 17.

Everything's Better In Song

"Duet" opens with a heartstricken Barry rewatching Singin' In The Rain, an uncontested movie musical classic.

Later on, Music Meister name-drops Fred Astaire and Frank Sinatra when describing how Barry passed the "rainy nights" of his youth, so it seems that Singin' In The Rain wasn't Barry's only musical obsessions. And speaking of obsessions, Kara's very set on The Wizard of Oz, making references to the movie throughout "Duet".

Commenting on the dream-like format of the episode, by quoting The Wizard of Oz Kara points out that this world features alternate versions of their friends and enemies. Unfortunately though, she can't just "click her heels", though Kara does try to persuade Millie to talk to her dads by saying "there's no place like home".

Waiting In The Wings

Repeating the exact same reference to Hamilton as Supergirl used earlier on in Season 2, Cisco-turned-Pablo tells Kara and Barry that he too is eyeing that spotlight, hoping to take his "one shot" and leap up on the stage someday.

This comes right on the heels of the revelation in the previous episode of Supergirl that on Earth-38, Hamilton's King George is played by an alien — and one who owes Alex a favor, no less. It seems that the musical sensation that is Hamilton is a multiversal constant, which is comforting in a way.

Star-Crossed Lovers

The star-crossed lovers trope is used well in "Duet", with this mini-musical about two youngster in love, in defiance of their warring gangster fathers. Barry's mind immediately jumps to the Romeo and Juliet adaptation West Side Story, but Kara opts for the niche off-Broadway musical The Fantasticks.

For a musical episode, "Duet" was actually fairly light on references, and I was particularly disappointed that there were no nods to Glee! considering that Melissa Benoist, Grant Gustin, and Darren Criss all starred in the popular musical show. I was also hoping for at least a passing reference to A Very Potter Musical, the college-made parody that shot Criss to fame. Alas (earwax), it seems that "Duet" was too busy putting on an excellent show to fulfill all my Easter Egg wishes.

Oh, and one more thing — Barry says that everything is getting "curiouser and curiouser" which is a quote from Alice in Wonderland. The animated Disney version of this book featured some great songs, but it's not known as being a musical classic, so minus points for references there, Barry. Stay on script!
