Elton John with Davey Johnstone, around 1975
Elton John (left) sings onstage while Davey Johnstone plays guitar. This undated photo was taken some time around 1975. Elton John was known during that era (and since) for his outrageous outfits, and you can't beat Johnstone's blue velveteen jumpsuit for its pure 1970s appeal. Davey Johnstone began playing with Elton John in 1971, and continued to back him for decades; in 2019, Johnstone celebrated his 3000th concert with John at a performance in Saskatoon, Saskatchewan.
