The news came from the CW’s TCA presentation, where executive producer Greg Berlanti announced a two-part musical coming late in the season. And that’s not all the excitement in store of DC’s TV-verse next year.
“Yes, there will be a musical crossover,”said Berlanti, via TV Line.“There’s going to be a musical pair of episodes in the back half of the year between Supergirl and The Flash.” He added that they’ll mostly be singing existing songs, but the writers have been kicking around trying to write “at least” one original tune for each episode.
You may also note that this announcement came exactly one day after our own Alex Cranz demanded a musical number, documenting the high number of singers in the DC/CW shows’ casts. And lest you think that she is not psychic, because she wanted all the shows and not just two, Berlanti also said he wanted to bring in characters from Arrow and Legends of Tomorrow into the show. A comment he capped with this:
"There's a lot of time travel shows. There will only be one time travel show where Victor Garber will sing Edelweiss." - Berlanti #TCA16

The panel also revealed that the Chris Wood’s pod-person, from theSupergirl cliffhanger, is Mon-El—who isn’t actually a Kryptonian in the comics. Also on deck? Sharon Leal as Miss Martian. Honestly, despite the decreased Cat Grant screen time, the CW is pulling out all the stops to prove it’s the right home for Supergirl.
