Please move along

I spotted this two part sign in a university office window along the walk from Teviot Place to the Meadows. I must admit I had noticed buskers there previously, but it seems to have done the trick because there were none there when I walked past. I did feel for the office workers - it's one thing having a bit of musical accompaniment while you work, but if it's loud and of dubious quality it can't be the best aid to productivity!
