Bassists are generally renowned for not moving much ... I suppose in terms of movement, they are comparing Hugh to Alec rather than any other bassist

I guess both Hugh and Alec have pros and cons really. Hugh seems to be more professional and make less mistakes (from what people say). Alec seems to look and act the part more, move around more, and contribute those ridiculously high vocals (which may either be a good thing or bad depending on your view)
