Drummer Nick Mason says Pink Floyd could have done things differently with Dark Side of the Moon.

Mason stopped by Abbey Road Studios in London last Friday for a playback of Dark Side, which was released 40 years ago this month. Afterward, he did a Q&A with members of the European press. First, Mason praised the album's engineer, Alan Parsons, saying, "Without him I think it would have ended up not quite as good."

But when asked if they should have done anything differently, he said, "What we should have done was we should have toured Dark Side for much longer, which almost certainly would have left us with a film of it... We have no record of what we did... it would have been great to play the whole thing beginning to end live a number of times and then recorded it. I think we would have sequenced it differently now, looking back on it."

Dark Side was recorded in Studio 3 at Abbey Road, where last Friday's event was held.
