This is a performance by my son's school band - all kids including the conductor. I'm sure I know the music but it's been bugging me for the past fortnight as I can't place it. I've asked my son but he didn't know the name of the piece he was playing.

Do you know what it is?

PS. the youtube video is worth watching till the end.

luuk ohm lozenge; piece of sucking candy, is the translation.

^So it's a thai tune called "ลูกอม" - correct?

...don't you just love 'em..these Thai music students are fantastic...especially when you see them marching and perfoming in parades..should be more of it..
