Deep Lancashire and Owdham Edge were combined and released as a CD "Deep Lancashire" a few years ago and should still be available - Topic TSCD 485. The trouble is that five tracks were missed off due to time constraints. Three of them were Harry's and two were the Oldham Tinkers'. Topic records have told me that it's unlikely that Harry's stuff will be put out on CD. The Tinkers are having their stuff re-released but under licence on the PIER label.
If you're lucky you can still get hold of vinyl copies of both Deep Lancashire and Owdham Edge from dealers.
