'I was yawning at nine o'clock because that is my bedtime'

If the on-field narrative stayed the same despite the altered playing conditions, then so too did the routine, rhythm and supporting cast that accompanies a Test in the UK.

The intervals remained the same length and even kept the names lunch and tea despite being shifted three hours backwards.

"I was yawning at nine o'clock because that is my bedtime," joked Cook.

"We are programmed to start at 11am when we play in white kit, but that is nothing more than a mental thing."

We are told on a regular basis that day-night matches become accessible to those who do not want to take time off work, that the stands will gradually fill with white collars arriving from the office.

The first day at Edgbaston did little to support that theory. The majority of the 21,649 that attended were there to see the first ball. Seats that were empty when play got under way remained vacant all day.

For most of the spectators, if any cricket was to be missed, it was at the end of the day, with some starting to file out about an hour before the players left the field.

Even the atmosphere followed the pattern of a normal day at the Test.

When he met the media on Wednesday, captain Root wondered how the famously raucous Hollies Stand might become even more rowdy after a morning in the pub and an extended evening of drinking.

But even the Hollies shifted its schedule, only fully finding its voice in the final session, just as if the Test followed regular hours.

For two sessions, it was quite sedate, but when it awoke, it was a spectacle in itself.

Cops chased robbers, then robbers chased cops. Mr Blobby led a conga line and the singing of Cook's name was loud enough to drown out the brass of Billy the Barmy Army trumpeter.

It might be that Friday and Saturday, usually the most chaotic, are when the Hollies goes bigger, earlier.

Has Test cricket found a new audience?

In all the similarities to a regular day of Test cricket, there is one difference that we can be sure of.

Of the 73,000 tickets sold over the first three days, Warwickshire say that 50% have been snapped up by spectators who have never before been to watch the longest form of the game.

Why has the day-nighter attracted a new audience to Test cricket?

"That it's the first day-nighter makes it more exciting," said Louise from Southam, who was attending a Test for the first time.

"If I enjoy it today, then I'd absolutely come back to another Test, even if it isn't a day-nighter."

Sometimes, the lasting impact of a historical moment doesn't reveal itself until long after the event.

The first tennis match under the Centre Court roof at Wimbledon held a significance because the retractable rain shield was always likely to change the way we watched events unfold at SW19.

Likewise, the first red card dished out by a referee was destined to be the first of many.

But, the first supersub in a one-day international, or the first football match settled by a golden goal have been forgotten because neither innovation caught on.

So, the legacy of this first day-night Test in England will only be revealed by the passing of time.

What next for the day-nighters?

It has not been played for the benefit of spectators, either at Edgbaston or watching at home, but to help the England team, who face day-nighters in both Australia and New Zealand this winter.

In 2018, India and Pakistan will be England's opposition in home Tests. Late finishes in the UK would not suit TV viewers in either of those countries.

The following year, Australia arrive for the Ashes. There may be a reluctance to tamper with that series, especially when ticket sales are usually incredibly strong for the visit of the oldest enemy.

The next day-nighter in this country could be 2020 at the earliest, with Warwickshire chief executive Neil Snowball even saying this match could be the "first and last".

"I can see it being successful in other parts of the world, but whether we need to in England is a different matter," said Cook.

"We're lucky in England that the crowds we get everywhere we play are fantastic.

"It's interesting and the players understand their responsibility to try these things."

The crowd in attendance is one thing, but domestic TV ratings should be monitored closely.

If Test cricket at primetime causes a spike in viewership, it is easy to imagine a scenario when broadcasters and administrators want more of the pink ball, especially when cricket's biggest ever rights deal has just been signed.

The pink ball and floodlights hint at a brave new world, but perhaps television will still be king.

The more things change, the more they stay the same.
