20 Sept 1968, Led Zeppelin (recording under the name of The Yardbirds) started recording their debut album at Olympic Studios, Barnes, London, England. The album took only about 36 hours of studio time to complete at a cost of around £1,782, with most of the tracks being recorded 'live' in the studio with very few overdubs. https://www.thisdayinmusic.com/.../led-zeppelin-led.../

'Led Zeppelin I' (1969)
No one seems to know the truth about Led Zeppelin's name, but we know it had something to do with the Who. Keith Moon joined Jimmy Page, John Paul Jones and Nicky Hopkins for Jeff Beck's superstar "Beck's Bolero" sessions in 1966, leading to chatter about forming a supergroup. There are two variations of the legend: Moon either fired back, "It'll go down like a lead zeppelin" or "It'll go down like a lead balloon," with the Who bassist John Entwistle adding the "zeppelin" bit. Source aside, the name stuck – and it inspired the the band's very on-the-nose first album cover: George Hardie's ink rendering of the burning Hindenburg airship, which adapted Sam Shere's black-and-white photo from 1937.
“The idea of it was to use the impact of this but use it in a graphic interpretation," Page told 'Time' in 2016.
