looking at this answer from oracle, i would say that we can safely assume coldplay are not going to perform at the grammys this year. the steve wonder tribute will be 2 days after the grammys.21 January 2015 / submitted by Tyler B, United States of America
Q. Hey Oracle,
My question for you today is: How do the band decide when it will be just Chris or the whole band while performing somewhere? For instance, Chris performed by himself at this year's Hope for Haiti but they have played at some benefit concerts all together.
THE ORACLE REPLIES >
It's as simple as logistics. It depends where the guys are and what's going on that determines what happens.
That's why their 2010 telethon performance was filmed in London but Chris was able to attend the recent benefit in LA.
