Published in 1978, it is one of the lesser-known and unfortunately underrated albums of solo Paul McCartney. In reality, it does not easily make it to the spotlight of reviews because it lacks a standout track that makes it memorable (the hit single was the long ballad built on synth and keyboard themes "With A Little Luck"), yet it contains excellent music and is significantly superior to the bestseller "Wings At The Speed Of Sound" from 1976, which, on the other hand, featured impactful singles (Silly Love Songs. Let Them In) but displayed creative scarcity in the other tracks.
It is considered by everyone a soft rock album and not without reason, as it was largely recorded by Wings in the Caribbean and later post-produced in London; the holiday atmosphere is felt in many other notable tracks like "I'm Ying" and "Cafe On The Left Bank". The album is largely written with Denny Laine, Wings' guitarist and Paul's sidekick since 1971, with this collaboration standing out in the experiments of "Morse Moose And The Grey Goose" and the acoustic guitar progressions of "Don't Let It Bring You Down"; the playful "Children Children", a charming little song sung by Laine about the carefree nature of childhood. The title track is remarkable, a portrait of the capital city that Paul paints with a few verses highlighting its characteristics ("Walking down the sidewalk on purple afternoon /was accosted by a barker playing a simple tune /upon his flute toot-toot-toot"
