Rose had form in the songwriting stakes (Somebody Loves me; Deep Purple; On a Little Street in Singapore and Bueno Sera among others) so it's not surprising he did a job on The Lamp is Low - as did Horsfall.
Allison Neale: “It’s difficult if you play mainstream in the UK, it isn’t appreciated enough. The current scene seems to focus on musician-composers.” - (Jazz Journal April 2013).
Liam Noble: “I know some people think playing standards is old-fashioned but I love it.” – (Jazz Journal January 2016).
