Nonsense, Paul and John were both intimately involved with the production aspects of their records and offering suggestions and tons of input on what they wanted. There are many books that describe the process they used in incredible detail on every song they recorded. Maybe you should read a few of those books before you talk. I own those books
Again...George Martin produced nearly every recording the Beatles made. Did they offer a suggestion or two?..Im sure they did, but which suggestions and on what recordings?..I nor you don't know and it's foolish to suggest otherwise...The production of all the technical aspects of the Beatles songs went to George Martin..Unlike the Beach Boys who later on were produced by Brian Wilson who was a mmber of the band

As an arranger[edit]
Abbey Road Studios, where Martin recorded Parlophone's artists
Martin's musical expertise helped fill the gaps between the Beatles' raw talent and the sound they wanted to achieve. Most of the Beatles' orchestral arrangements and instrumentation (as well as frequent keyboard parts on the early records) were written or performed by Martin in collaboration with the band.[34] It was Martin's idea to put a string quartet on "Yesterday", against McCartney's initial reluctance.[34][35] Martin played the song in the style of Bach to show McCartney the voicings that were available.[36] Another example is the song "Penny Lane", which featured a piccolo trumpet solo. McCartney hummed the melody he wanted, and Martin notated it for David Mason, the classically trained trumpeter.[37]
Martin's distinctive arranging work appears on many Beatles recordings. For "Eleanor Rigby" he scored and conducted a strings-only accompaniment inspired by Bernard Herrmann. On a Canadian speaking tour in 2007, Martin said his "Eleanor Rigby" score was influenced by Herrmann's score for the Alfred Hitchcock thriller, Psycho.[38] For "Strawberry Fields Forever", he and recording engineer Geoff Emerick turned two very different takes into a single master through careful use of vari-speed and editing.[39] For "I Am the Walrus", he provided a quirky and original arrangement for brass, violins, cellos, and the Mike Sammes Singers vocal ensemble.[40][41][42] On "In My Life", he played a speeded-up baroque piano solo.[43] He worked with McCartney to implement the orchestral 'climax' in "A Day in the Life" and he and McCartney shared conducting duties the day it was recorded.[44]
He contributed less noted but integral parts to other songs, including the piano in "Lovely Rita",[45] the harpsichord in "Fixing a Hole", the organs and tape loop arrangement that create the Pablo Fanque circus atmosphere that Lennon requested on "Being for the Benefit of Mr. Kite!" (both Martin and Lennon played organ parts for this song), and the orchestration in "Good Night".[46][47][48] The first song that Martin did not arrange was "She's Leaving Home", as he had a prior engagement to produce a Cilla Black session, so McCartney contacted arranger Mike Leander to do it. Martin was reportedly hurt by this, but still produced the recording and conducted the orchestra himself.[49] Martin was in demand as an independent arranger and producer by the time of The White Album, so the Beatles were left to produce various tracks by themselves.[50]
Martin arranged the score for the Beatles' film Yellow Submarine[51] and the James Bond film Live and Let Die, for which Paul McCartney wrote and sang the title song.[52]
Paul McCartney once commended Martin by saying: "George Martin [was] quite experimental for who he was, a grown-up
