Like I said, memory is hazy.
It was just the band in a hot dark room for quite a long time.
5 days a week, yeah, probably 10am-6pm, although these things are always fluid, some days shorter, others longer.
I seem to remember I didn't know what we were going to do each day. Maybe some days I was told the evening before to check out a song for the next day. Can't remember.
Towards the end, maybe the last week or last two weeks, we set up in a bigger room with the full production - monitors, PA and lights, so the crew could work on their set up.
None of this was that extraordinary to me.
Paul McCartney had his own rehearsal space. We had finished his new album, then set up in the rehearsal space. We probably spent a month just jamming, trying out songs from his repertoire, all the while making videos for the singes of the album, plus at least one documentary, plus magazine interviews. We kind of rehearsed for Paul's tour for 4-6 months, while doing tv appearances, interviews, videos and documentaries.
