Elton John and Aretha Franklin celebrate milestone birthdays

Franklin turns 75, while John celebrates his 70th.

— -- Two music legends are celebrating milestone birthdays on Saturday.

John's career took off after he teamed up with lyricist Bernie Taupin in 1967 and began creating what's become one of the most successful catalog of hits in music history. Starting with 1971's "Your Song," John's impressive string of hits spanned well into the 1990s.

Franklin, of course, is the Queen of Soul. A pastor's daughter, she developed her powerful voice singing gospel at her dad's Detroit church before turning to secular music. Her career skyrocketed after she signed to Atlantic Records in 1967, scoring early hits like "Respect," "Chain of Fools," "(You Make Me Feel Like) A Natural Woman" and "Think."
