Et tu, Brute?

T.I.M. could stand for The Ides of March, which this year happens to coincide with T.I.M., The Improvised Musical.

This month, Nevin Langhus, of Running With, joins the ensemble, to perform a one-time-only made-up-on-the-spot Broadway-style musical (singing, dancing, the whole shebang) based on a suggestion from the audience.

As in every monthly show, the cast is accompanied in its improvisation by The Improvised Band.

There’s nothing like it around. It’s $5 and starts at 7:30 p.m., Thursday, March 15, in the arena at ComedySportz, 420 S. 1st St.
