While i will certainly agree that close order drill is pretty useless at present (it actually was useful in the 16th-early 19th centuries), I totally disagree on bands! (Okay, bias time here - my father played in the CF band in Korea).
First, they are actually pretty good for morale and, let's face, why contract out what you can have internally ?
Second, a really, REALLY good band means pipers.... lots and LOTS of pipers... a WMD (Weapon of Mass Deafness) that has never been outlawed by the Geneva Conventions and can (and has) been put to use with great effect in a number of both riot and battlefield conditions.
