Ive stumbed across a pretty good bootleg of the Eugene concert which i converted to mp3 from FLAC. Anyhoo - gave it a VERY quick listen and apart from the pretty good soundquality - was i mistaken and there was duet during Sailing To Philadelphia? There seemed to be another singer representing Mason? im sure any "guests" will have been all over the diaries but i was steering clear of these as i didnt want spoilers -
Who was this guy - sounded quite American - or did it imagine it all!!??
