Amen to this. I will also add chord changes. I've been in situations where the monitors were crap, and all I could hear was either the bass line or rhythm guitar/keyboards. Knowing the chord changes helped me stay with everyone else.
There are, of course, times when people are not playing together. In cases like that it was up to me to provide cues for where the band should be in the song. But I could only do that if I memorized all the other elements.
