The 'classic' breakfast was very much what British people ate in the past when the ingredients were cheap and working hours much longer than today's. These days the items are much more expensive and most people, including myself, have much simpler fare and quicker to prepare.
IMHO superior to the English breakfast is the Irish version with both black and white puddings. Better still, as a personal taste, the best breakfast of all is undyed smoked haddock with a poached egg.
All such things much easier when someone else does the cooking whilst staying in an hotel etc.
