John, Read Bell's paper and you will see it is rife with QM language: http://www.drchinese.com/David/Bell_Compact.pdf He also always uses "the value" or "the result" when talking about a measurement, which implicitly references the notion of collapse.
"With the example advocated by Bohm and Aharonov, the EPR argument is the following. Consider a pair of spin one-half particles formed somehow in the singlet spin state and moving freely in opposite directions. Measurements can be made, say by Stern-Gerlach magnets, on selected components of the spins o1 and o2. If measurement of the component o1 * a, where a is some some unit vector,* yields the value* +1 then, according to quantum mechanics, measurement of o2 * a must yield -1 and vice versa." Under many-worlds a measurement does not result in a single outcome. Above, measurement of o1*a would yield both +1 and -1, seen and experienced by the observer who measured o1. The two particles had already measured each other and so the other particle is known to be correlated with the opposite result. The particles carried their correlations at sub-light speeds across space, and the results and effects of measurement spread only at light or sub-light speeds. If you remove Bell's assumption that measurements have single outcomes, the rest of his reasoning that interpretations must be non-local or unreal becomes unfounded.
