In september and november of 1967, scream the last scream was played live and recorded by the audience. There were also 1 or 2 recordings of scream the last scream by the BBC. As for vegetable man, i think it was only recorded at the BBC.When it comes to official releases: they were only released as solo tracks by Syd. There are some of those 'outtakes' RoIO's which contain studio versions of the songs by Pink Floyd. And on very early live RoIO's (from 1967, I think) the songs are played live by Pink Floyd.
I think both should be added, personally. I mean, they were both studio recorded and they were both played live with all of the original members of pink floyd.
I'm guessing you mean soundboard/commercially released live concerts? Because that would be quite a list you'd have to put together if you took into account roios :pI think that would make it very confusing. Therefore, here's the good news. After this one is done, and I hope it's a success, I'll start one on the live versions of Pink Floyd
