Kev,

> Am I wrong in thinking that for there to be phase issues multiple tracks must be involved? <

You already got all the right answers, so I'll clarify just one point:

Phase shift by itself is a total non-issue. The only time phase matters is when audio is combined with a phase shifted version of itself. As in the examples of multiple microphones on one source, or reflections off a glass window. In those cases what is audible is comb filtering, which is a series of peaks and deep nulls in the frequency response. Phase shift by itself is totally benign.
