BTW Andy, we just had a mega rehearsal sesh with our new vocalist Jade - flippin' 'eck she's good! As we have another Mini LeFunk! gig on Friday we used backing tracks again, but I can assure you the 5-piece does this song every bit as well (OK, our drummer tends to add unnecessary fills but that's what drummers tend to do, unfortunately).
I'm posting this mostly for your benefit as it is - for me - an interesting bass exercise. The bassline is very simple but the challenge is to make it sound almost like programmed bass without changing any amp/bass settings, so it's all about how the strings are hit. This rough mix places the backing track a little high and bass a little low - I forgive Dave the guitarist (who did the mix) as he's going down with a cold and did this very quickly before tucking up with Lemsip - but the effect of the bass seems to be OK.
