BLINQ are Natalie Williams (first solo/ leading)/ Liane Carroll (second solo), Brendan Reilly, Ian Shaw, and Gwilym Simcock (piano/ arranger. The song is a Natalie Williams/ Tom Cawley composition. I have a recollection that this song  started off in early performances in 2011 as the ‘Good Old Days’. Video from the  Ronnie Scott’s Youtube Channel.
