"Junk" offers a reflective look at discarded items in a junk shop, from "parachutes" to "sleeping bags for two," and the "candlesticks" and "building bricks" that populate its verses. The chorus, with its contrast between the shop's invitation to "Buy, buy!" and the junk's lament of "Why, why?", evokes a sense of forgotten purpose. This song can be seen as a meditation on the fleeting nature of life and possessions, with some speculating it even touches on the emotional landscape surrounding the Beatles' eventual breakup. Paul McCartney began writing this piece in 1968 while in India, and it later found its home on his 1970 debut solo album, McCartney. Playing this song can feel like holding a quiet, poignant conversation with the past.
