Taylor Swift covered for Dave Grohl when he was too high to play with Paul McCartney

Dave Grohl was doing an acoustic show and told a story about Paul McCartney and Taylor Swift… and pot.

He said Paul wanted to jam but Dave was stoned and couldn’t play piano… and all of Paul’s guitars were left-handed.

He said, luckily, Taylor Swift swooped in to save the day and took over the piano. She started playing “Best of You”.
