John Lennon and Paul McCartney wrote several of The Beatles’ biggest hits. A few songs were written in unique places that wouldn’t usually possess the best songwriting atmosphere. However, McCartney and Lennon often wrote songs whenever inspiration struck, and the two wrote one of their earliest hits while riding a tour bus.
The Beatles formed in 1960, but it took the band two years to get their first big hit with “Love Me Do.” Their second single, “Please Please Me,” reached No. 2 on the UK Singles Chart. The Beatles were on the rise following that song and later went on tour as the supporting act for singer Helen Shapiro. In Anthology, John Lennon said he and Paul McCartney wrote their third single, “From Me to You” on the tour bus.
