Lots of inaccuracies - when Brian started dropping LSD, Carl taking over after Smile failed, Brian working on Love You simultaneously with 15 Big Ones, Brian singing lead on Life is for the Living, Al and Mikes vocals on Love You coming from earlier sessions, Mike’s response to hearing it in the studio for the first time (that’s a story Ove never heard).
The latter is in Carlin's book, IIRC. Also, the reference to Al and Mike's vocals is in relation to Adult/Child, probably referring to On Broadway for Al.
