30 day music meme. Day Seven - A song that reminds you of a certain event

I had a lot of trouble with this one, as the songs I remember for certain events were linked to them afterwards, and I wanted to think of one that was present at the actual time.

And then I thought of the Year 10 trip to Canberra in 1979, and the constant playing of one particular tape - ELO's "Discovery".

So for a song that reminds me particularly of that trip, ( The Diary of Horace Wimp )
