The Independent Film Channel, cable TV's home of "Dinner for Five" as well as other independently produced films, will air David Malver's drum corps documentary "Hard Corps" on Monday, March 29. You can check out the broadcast schedule at the IFC's Web site -- the air time will vary depending on which time zone you're in. On the East coast the film will show at 8:30 p.m. For those New Yorkers who get RCN cable it'll be on Channel 30. Midwest folks, tune in at 7:30 p.m., Mountain Time 6:30 p.m., and Pacific time 5:30 p.m. The film, produced in 2000, follows two Cadets snare drummers through their age-out season, and is an emotional and telling look inside the trials and joys of becoming, performing with and finally leaving the Cadets.
