Composed In August

I tried to link to a Scottish chap reading Burns, but it doesn't seem to be allowed. You'll have to go to the BBC page and then click the thing marked "Paul Higgins".

There's a sung version here: http://www.youtube.com/watch?v=kFO2ldO3Ga0

I like Burns' explanation:

A charming Filette who lived next door to the school overset my Trigonometry, and set me off in a tangent from the sphere of my studies.
