The poet uses a harsh tone when he tells us that “the bulldozer breaks raw bricks to powder”. The resurrection of the city during the building programme was not achieved without pain, which comes out in the use of the word "raw". Glasgow’s previous state is clearly significant as it will always be missed by the inhabitants of the city. Towards the end of the poem Iain Crichton Smith finally accepts that “buildings sail into the future”, and the tone becomes more upbeat showing he has finally accepted that things change. The use of the word “sail” shows confidence and therefore also establishes the optimistic tone. The poet remembers the “old songs you sang”, a symbol of Gaelic culture, which shows that although trends change, the past will always be remembered. In the last line of the poem, the poet reflects on the changes music has experienced over the years, “scale on dizzying scale”. This line is a pun as it reflects on both the pop music that is around at the moment due to the changes music has been through during the years, and also the sheer scale of changes that have occurred. The poet is accepting the changes Glasgow has experienced over the years, and how significant this has been.
