[Note 1] It was the ambition of the early steam coach engineers to establish services from London to the leisure resorts of the wealthy. This song pre-dates any of the successful attempts.
[Note 2] Ben Wilson writes of the Regency period that "Well-off Britons were assailed from all side by new needs and wants. [Dr Thomas] Beddoes [a fashionable doctor] wrote that a scream pursued one throughout the day : "did you see the papers today ? Have you read the new play - the new poem - the new pamphlet - the last novel?" every day there were must have new inventions advertised in the papers: labour-saving corkscrews, novel candle snuffers, even a hunting razor so that busy gentlemen shaving at full gallop need not miss a second of sport. It was a particularly British habit to lavish money on gadgets for which they had no conceivable need." [Wilson, B. Decency & Disorder: the Age of Cant 1789 - 1837; p25]
[Note 3] "As they as will can go up hill, for which they have propellers, too" 1825 John Seaward and his brother Samuel Seaward granted a patent for 'propelling locomotive engines, vehicles, and other carriages...a steam-engine' https://www.gracesguide.co.uk/Timeline:_Steam_Road_Vehicles
[Note 4] This may be a reference to a carriage built by David Gordon in 1824. The legs extended through the floor in the middle of the carriage, analogous to the legs of a horse, and the feet pushed backwards on the road to move the carriage forward. Friction was still poorly understood and engineers were not confident that the wheels alone would exert sufficient traction to move the carriage.

[Note 5] Seats inside the coach cost more than those outside. See the illustration of the coach built by Goldsworthy Gurney in 1827 the illistation appeard on the front of the Morning Chronicle 10th December 1827 many newspapers reports throughout 1827
[Note 6] It was common for the self-employed (and indeed some employees) not to work on a Monday; a practice known as keeping St Monday
[Note 7] The dangers of accidents generally and boiler explosions in particular were well founded. See Bar271 The New Steam Carriage Blown Up.
[Note 8] "Now bawling loud, among the crowd, came Patrick Denny" - Patrick Denny has not been identified but presumably he would have been known to the song's intended audience
[Note 9] The song Adventures in a Steam Boat was printed several times under various titles.
