"Changes" is a song by English singer-songwriter David Bowie, originally released on his 1971 album Hunky Dory. RCA Records then released it as a single from the album on 7 January 1972. Written following his promotional tour of America in early 1971, "Changes" was recorded at Trident Studios in London between June and July that year. Co-produced by Bowie and Ken Scott, it featured Strawbs member Rick Wakeman on piano and the musicians who would later become known as the Spiders from Mars: guitarist Mick Ronson, bassist Trevor Bolder and drummer Mick Woodmansey. The song also marks the first instance of Bowie playing the saxophone on one of his recordings.
