In reply to thommi:
No, he was Kirsty MacColl's dad, though, who's mum was his second wife. His 3rd wife was Peggy Seeger, and their son Neill MacColl's David Gray's guitarist. His grandson Jamie MacColl is in Bombay Bicycle Club.
A lot of songs that seem to get listed on the web, and even in books and song collections, as "Trad Irish" were actually written by Ewan MacColl. Songs like:
Shoals of Herring (written about Yarmouth herring fisherman, and "back-tradded" to being supposed to be Irish, then further "back-tradded" when the song "Shores of Erin" was created from it and now often mistakenly thought to be the inspiration for "Shoals"!)
Dirty Old Town (about Salford but again aoften listed as Irish)
Moving On Song (often thought to be a trad Irish Traveller song)
Kilroy Was Here
Paddy West
Born In The Middle Of The Afternoon
Other songs he wrote that he hardly ever gets recognition for are:
The First Time Ever I saw Your Face (dictated over the phone from UK to USA by him to Peggy!)
Fourpence A Day (usually thought to be Trad Geordie)
And of specific interest to climbers and mountaineers:
The Manchester Rambler
Joy Of Living (which will be sung at my funeral)
