Watch: The Flash Musical Crossover Clips
If you happened to tune into last night's Supergirl and ended up a bit disappointed, you're not the only one.
Not only were there audio issues throughout the episode, but there was no singing.
It's the second time they pulled a bait-and-switch on us, as they did the same with the Invasion crossover episode which the Supergirl episode had nothing to do with.
The good news is that the musicial crossover takes place tonight on The Flash, featuring Grant Gustin and Melissa Benoist reuniting their voice boxes from Glee.
The CW released preview clips. Watch below.
The Flash airs Tuesdays at 8pm ET.
