Suppose The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison, and Ringo Starr, they became widely regarded as the greatest and most influential band in popular music history. They are often cited as integral to the development of 1960s counterculture and the recognition of rock as a legitimate art form.
Can we infer that "The Beatles had a different lineup before the final four members."? Yes, no, or maybe?
