"I Can Do That" is a song from the musical A Chorus Line.
As with the rest of the musical numbers in A Chorus Line, this song was inspired by real-life stories of dancers.
CityBeat explains "nervous Mike...tells how he took over his sister’s dance class opportunity".
[1] TheatrePeople described the musical style as "lively jazz swing",[2] while MovieMet called it "an energetic, post-Vaudevillian song-and-dance" and added it "will remind film fans of Donald O’Connor’s “Make ‘em Laugh” routine from “Singin’ in the Rain”".
[3] Dance Informa deemed it a "potentially exuberant number",[4] and Stage Whispers described it as "cute".
