Challis, if you're willing to do a little digging, that link to Google will work.

I found a reference to the Tom McEwan you were looking for at a heading marked "playlist" by following some links I got to the Edinburgh Songwriters showcase founded by Tom.I couldn't get through on the link provided for Tom there as it was taking too long to connect.I'm sure you could eventually find him.

In the meantime there are some really cool sites on noctilucent clouds and aurorae.
