Neither, Lois and Clark have too much respect for musicians who earn their living through music to promote and support something as evil as karaoke. In fact she'd probably be in the forfront to boycott those club owners too cheap to hire real musicians and use karaoke as a substitute for 'live music'.
Lois can sing, but I think, except for one well-done fic, it's considered the accepted that Clark can't carrry a tune in a very large bucket.
Tank (who thinks that karaoke should be legislated against but if Lois or Clark did such a despicable thing they'd probably choose an old standard as Lois did in IGACOY)
