Sir Eton John and Billy Joel have toured together on several occasions
Sir Elton John and Billy Joel have been forced to cancel a second joint concert after Joel fell ill.
The pair have pulled out of Monday's date at the Times Union Center in Albany, New York.
They had already called off Friday's show on their tour when Joel was told to rest after coming down with "flu- like symptoms" and "extreme fatigue".
Details on rescheduling the concert dates are expected to be announced in the coming week.
Sir Elton and Joel have been touring together for two months under the banner Face 2 Face, selling out arenas across the US.
During their concerts they take to the stage for a series of piano duets, before going on to sing some of their biggest solo hits.
The pair first began performing together in 1994, and this time are planning to travel the world playing together on and off for at least two years.
