You ask in past tense, and for sure not every single have the chorus come in that fast, but you gotta consider the proper framework for this question.
The reason why choruses need to come in quick is because radio listeners are zapping you real fast, if you don't hook them. So (1) the 'clock tyranny' mainly applies for Radio hit singles. Secondly, it's also about listeners expectation to the particular genre, and in pop hit singles you'll need the chorus to come in, not before 1:10, but before :50 and preferably :35. In rock and country I think you'll have slightly more sec's, but not many. In death metal... I just don't know, and will be burned in hell

But for music aimed at radio (and not all are), if the song title AND the chorus is not within 1min, there better be a damn good reason (perhaps due to the lyrics or arrangement), as this is something a&r consider as basics.
There's a whole science supporting these 'rules' (The former company Polyphonic HMI now in the shape of Uplaya:

For songs to be eligible on the Radio, they just need to comply to the format they require. Same thing with listings for production music, and other genres. Format is very much based on commercial requirements, because the music has to be used in a specific context.
In the book Futurehit DNA, the author discusses the reasons and prospects of this subject in commercial music

Im not saying that I agree well with this, only that in commercial music you HAVE to deal with the format requirements of clients. If there's any learning from doing Taxi, this is one of them, IMO. The Beatles were well aware of this, and Hey Jude is NOT a representative example, as it's written in the AABA form (verse, verse, bridge, verse) and therefor doesn't have a chorus section at all.. How about:
Love me do, chorus at :28
She loves you, chorus at :13
Eight day's a week, chorus a:34
Ticket to ride, chorus at :34
Goodbye hello, chorus at :38
Get back, chorus at :39
(this analysis was made by James Linderman, article found at SongU)
Aledgedly John and Paul used to makes jokes about writing a 'swimmingpool', so I believe they were VERY well aware of commercial song forms, and what works ect.
Song form and commercial formats are not anti-art, they are just means to help you understand commercial requirements, helping you to get your music to the places you want it to be. When you're a band and play live, you have the listeners where you want them, and can play 25min versions, if you please (just make sure they have enough beer

), but in radio you don't have listeners tunen into you and YOU have to hook them in. Not an easy task when all they want is local news and forecasts, according to ASCAP VP Ralph Murphy
