I think the linguistic version of his message would be 'its not what you say but how you say it'. Which is obviously also bollocks. For example, theres no way to say "What a load of bollocks" and have it not mean that what you just saw is bollocks. You can sugar it with your tone of voice, soften the blow of the meaning of the words, or make it vicious, but it means the same thing.
Yes, the way you say something (expression, feeling, tone, vocally and musically) is extremely important, but not the neglect of the words (notes and beats).
And it is very ironic, and he does seem to mainly be saying "I'm stoned".
