The Boston rockers performed all of their 1975 classic 'Toys in the Attic,' save for the album-closing 'You See Me Crying,' during the first two concerts of the trek and issued an official statement to that effect on Monday. But guitarist Joe Perry also told Reuters during the weekend that the group plans to switch in a couple of weeks and play 1976's 'Rocks' in its entirety. He did not say whether the group would stay with 'Rocks'or alternate the albums in their set for the duration of the tour -- or even work in another of the band's albums in its entirety.

Perry also said that frontman Steven Tyler found it too difficult to sing 'You See Me Crying' right now but is working on it and may add the song in future shows.

Perry also predicted an early July return for guitarist Brad Whitford, who sidelined after surgery to relieve internal bleeding after hitting his head while getting out of his Ferrari earlier this month.
