I am a Welshman (a harp being our national instrument) living in the English village of Welwyn (which is 'old' English for willows). So it seemed to be a good fit.
More piously, 'a harp from the willows' is a symbol of faith and hope derived from Psalm 137:2. There, the people of Israel in Babylon hang their harps on the willows in sadness at their exile. To 'take the harp from the willows' is to begin to sing again. It expresses hope, faith and joy in expectation of God's deliverance. I would like to think of my blog being a promoter of faith - my own and that of others.
Then again, if people accuse me of 'harping on...' about something - I've got there before them.
