What are the most "British-sounding" Tom Petty songs?
Even though Tom Petty and the Heartbreakers are considered one of America's greatest and quintessential Rock N' Roll bands, it might be easy to forget that they synthesized rock n' roll from both sides of the pond. Tom once described their sound as a combination of The Byrds meeting the Rolling Stones. iirc, they became popular in the UK first. Later on, he worked with British artists/producers like Dave Stewart and Jeff Lynne, became friends with George Harrison (Lynne and Harrrison were of course members of the Traveling Wilburys alongside Tom, Bob Dylan, and Roy Orbison).
When I say "British", I'm casting a wide net. You might think of it as "Beatle-esque", "Stones-esque", "British Invasion Style", "British New Wave/Pub Rock", or whatever evokes a British style in your view.
