7 O'Clock Train for 7 flutes in blues-boogie format is always likely to be a winner. 3 piccolos really add colour to this arrangement which is very much safety in numbers rhythmically. Parts 1-3 and 4-7 function as 2 answering groups so there is plenty of scope for encouraging everyone to have a go here. There is an optional chord accompaniment sheet but it isn't at all necessary. Great fun and well worth the money.
