Mr. Night has a dream: Someday, the sing-along will make a comeback. If people will fawn over lip-synching "performers," they'll go ga-ga for a return to the elementary-school classic of everyone in the room singing the same song, regardless of each individual's vocal talent. The Kevin Kurth Show is a first step in this healing process. Kurth performs a 6 to 9 p.m. show at SPOT nightclub (4146 Manchester Street; call 314-371-1330 or visit www.spotbar.net for cover charge information) involving Broadway classics, standards and customer requests (all performed solo), as well as the throwback group songfest. After a few drinks and a few rounds of "Get Happy," your week is going to look so good you won't even believe it.
