Working with Paul McCartney would be a dream for many musicians. He proved himself to be a talented musician and songwriter with The Beatles. Some of their most notable songs feature only Paul by himself. Collaborating with the bassist wasn’t a bucket list item for guitarist Chris Spedding, but he said Paul’s whining proved how different he was from other musicians.
The closest you could get to a Beatles reunion in the mid-1980s was getting two of the remaining three members in the same studio.
Since George Harrison paused his solo career after 1982’s Gone Troppo, that meant Paul and Ringo Starr. And Paul was the only option since Ringo spent most of the decade on the sidelines, too.
