Ah na alala ko na po. It's Chicago Live in Toronto - Liberation ang Last Track, where Terry Kath ..well Man, was getting spaced out and all this pre-Vai effects were just everywhere.
As said, the songs were more sped up like 'Does Anybody Know..' Ta ta ta ta taaaaaa..
And the introduction went like " These guys are not coming up unless you give it up for them..Ladies and Gentlemen.. Chicagooo Chicagooo..."
