'Jeopardy' Included A Question About 'The Flash' & 'Supergirl' Musical Crossover

The Flash and Supergirl's musical crossover delighted plenty of Arrowverse fans when it first debuted earlier this year. And now, it looks like Jeopardy has even caught wind of the trend.

The iconic quiz show featured a question about the musical crossover, "Duet", in their December 21st episode. The question read "Grant Gustin and Melissa Benoist sang 'Super Friend' when these 2 heroes met in a 2017 TV episode."

According to Arrowverse fans, the contestant ultimately got the answer correct, answering "What is The Flash?"

While "Duet" might not have resonated with every Arrowverse viewer, it found its audience, largely thanks to its delightfully catchy roster of songs from La La Land and Crazy Ex-Girlfriend alums. But according to The Flash star Danielle Panabaker, there are not any immediate plans to bring another musical crossover to life.

"To the best of my knowledge," Panabaker, who plays Caitlin Snow/Killer Frost on The CW series, explained earlier this year, "we're not going to do that again this year...That musical was pretty ambitious. I think by the time we finished the musical, we were pretty exhausted."

If you want to relive the magic of "Duet", its soundtrack is now available on iTunes, Google Play, and the like. If the non-musical crossovers are more your speed, The CW is providing a chance to revisit the newest one, when it will re-air all four portions of "Crisis on Earth-X" on January 8th and 9th.

Supergirl and The Flash return from midseason hiatus on January 15th and January 16th, 2018.
