Blur star Damon Albarn is worried the band will struggle to replicate their 1990s success when they reunite this summer (09).
The Britpop pioneers announced in December (08) they would return for a series of gigs in London in July (09) following a six-year hiatus.
But frontman Albarn is concerned the group will fail to perform classics such as Parklife and Country House as well as they did a decade ago.
During an appearance on a BBC radio show Albarn played a 10-minute clip of a set performed by the group in 1997 and declared, "This is one of the highlights of being in Blur. I'm going to have to work hard to get back to that standard."
