C'mon....!! lets not get carried away here. OK, you did not like Cream, but it was impossible to tell from their music, what their personal feelings were for each other. Baker hates everyone..always has...but Bruce and Clapton got on quite well.
I love me some live Cream, but I'm going to have to disagree with you. Live they'd pop into "three guys playing three different songs" mode quite often.
They'd all stay in key mostly, but you can hear they're not listening to each other much by 68 or so.
I know Ginger and Eric have some story where they complain about that. Iirc they both stopped playing completely on a show that year and Jack was turned up so loud he didn't HEAR them stop playing and just kept blowing.
