Ah, here's the text of the email:

On 18th March 2016 Topic will proudly release the latest volumes in the widely-acclaimed ongoing series of traditional music from these islands, The Voice of the People; nearly 200 tracks of the most vital, dynamic music made by Irish immigrants in London over the last six decades make up two 3CD sets:
• TSCD679T "It was mighty!" There wasn't a corner of what was to become Greater London in the 1950s where there wasn't some Irish music to be heard, if you knew where to find it. This special collection of recordings presents and explores the fine examples of the music-making of those immigrants from rural Ireland who settled in London in the first couple of decades after the War.
  
• TSCD680T "It was great altogether!" This compilation explores the traditional Irish music which has continued to secure a place for itself in London throughout the last fifty years; demonstrating both the "old" music, completely untouched by the goings-on in Irish popular music, and the traditional music from the current scene led by second and third generation musicians.
