The other night I was watching a documentary about Mae West and I heard her sing a song called 'My Old Flame' 1934 - IMO It's a song about pretending not to be bothered about an important part of the past - it suited her haughty ways and undermined them at the same time - It was obvious she knew this and played on the irony ...the second line is the killer ... Then I discovered this version by Billie Holliday 1944 and I Immediately thought that it should've been on 'As time goes by' - The poignancy, irony and humour of the song would've suited BF perfectly and lets face it there is definitely one particular old flame that would fit the part....
