Tally is absolutely coming to sing. She has double vocal chords and part of her kind of witchcraft is in vocal work so she probably does all right at the microphone!
Raylan did not realize it was karaoke night and was there to have a couple of drinks.
Lucifer showed up to give Nyx a friendly hard time but also because the Devil loves a spotlight and also to show Chloe what the nightlife is like outside of Lux and to sing at least one duet with Sabrina.
Major was told by Liv that he has to come and he is not going to complain. I'm guessing Ravi was pulled into this two because Three Morgueteers! (You love it, Ravi.)
Danny, Riggs, or Jacob could be there as well! I just didn't have anything in particular fin mind for them.
