This is a summary of Ewan MacColl from The Working Class Movement Library that is located in MacColl’s home town of Salford. The Library's holdings include material from all aspects of Ewan's political and cultural life

Ewan MacColl will be known to most people as a songwriter and singer, but he was also of significant influence in the worlds of theatre and radio broadcasting. He was a committed socialist all his life and his political sensibilities underpinned all his creative activities.

To me it seems a very fair synopsis of his life. It is hardly surprising he was a political animal considering his background:
Ewan MacColl was born James Henry Miller in Salford, Lancashire, on January 25 1915. His father, William Miller, was an iron-moulder, militant trade-unionist and communist who had left his native Stirlingshire in his mid-twenties. His mother, Betsy Hendry, was from Auchterarder, Perthshire. Both parents were active left-wing socialists and from his earliest days, MacColl was familiar with the cut-and-thrust of political discussion and argument. Equally important in the life of the household were the songs and stories his parents brought from Scotland – a huge repertoire with which his father and mother kept themselves and their friends entertained.
I wonder if his creativity was in part motivated by his politics?
If satisfied with the status quo would he have had the drive to produce his body of work?
