Elton John Announces Farewell Tour

Elton John is giving touring one last shot, and then he's saying farewell to life on the road.

Elton just sat down with Anderson Cooper to announce a world tour, saying it'll span over the course of the next 3 years. The singer says he wants to spend more time with his husband, two kids and family so he's calling it quits.

The 70-year-old legend has been on the road for almost 50 years. His first big hit, "Your Song" was released in 1970.

What's unclear ... will he continue his Vegas residency after his farewell tour?

One thing we know ... he won't stop performing. Our Elton sources say the announcement is ONLY about touring.
