"Penny Lane" is a song by the English rock band the Beatles that was released in February 1967 as a double A-side single with "Strawberry Fields Forever". It was written primarily by Paul McCartney and credited to the Lennon?McCartney songwriting partnership. The lyrics refer to Penny Lane, a street in Liverpool, and make mention of the sights and characters that McCartney recalled from his upbringing in the city.

Arranged standard brass quintet.

I have made the decision to arrange this piece in Bb (The original is in B)

This means the trumpets are playing in their brightest register, for both the verse and chorus.
The solo (piccolo trumpet in the original) is played on standard trumpet using harmon mute, and drops it down an octave. It still sounds "brilliant"
The mp3 extract is of the verse and the solo.
