John was talking about 1 day, but i can hardly imagine the americanas would come over for just 1 day. Maybe John and Mike 1 day and the rest a week?
Guy hasnt answered yet
Mike and John are quite handy as they are in the UK with fast trains and planes to get to London anyday they are needed.
Americans are other story, if they come is because at least they are working a week.
It's easy that in order to fit all schedules Mike and John went one day or two to play on their songs and the rest remains for the remaining songs.
