Lightning in volcanic eruptions is, I believe, rather common. The ash sent up in the volcanic plume is flowing upward at a furious rate - as the dust particles bump into each other, they rub off electric charges, and eventually set up what is effectively a big voltage between the cloud and the surrounding air (or the cloud higher up). Eventually that voltage difference becomes large enough that the air can break down and BAM - you got lightning.
Same thing happens in thunderheads - the air currents driving water molecules in a convection pattern inside thunderheads generates sufficient voltage differences that lightning (air breakdown and electrical connection across that broken-down air path) can strike.
