I had in mind Swan Arcade's three-part harmony version of "Lola"

I remember their performance of this song with affection. We booked Swan Arcade (Dave & Heather Brady and Jim Boyes) on a number of occasions. All excellent singers and with really sure and sometimes quite chilling harmony singing. They had a catholic approach to repertoire; largely traditional but they had no problem in placing Dives & Lazarus next to a piece of intelligent, quirky, funny songwriting like Ray Davies' Lola or Weary Whaling Grounds next to Paperback Writer. Their interpretation of these pop songs enabled them to be seen in a different light and the trad-loving audiences that we attracted could recognise the way they had arranged the harmonies for these songs had been achieved with care and skill... and yes, these "always went down a storm" but no more so than their arrangements of traditional songs. Nobody thought that they were inappropriate.
I was very saddened by the death of Dave Brady. The musical skill and the thought with which he brought to his singing and group arrangements was exceptional.
