We report on recent observations of molecular clouds in the tidal Magellanic Bridge; specifically, the Ы?kpc-long, tidally extended "tail" of the Small Magellanic Cloud. In particular, we identify an unusually high 12CO(3-2)/12CO(1-0) ratio of 2-3 to 1, toward one of the clouds, suggesting a warm and dense molecular material associated with imminent or current formation of stars. ...
