the chain for me when I first picked up the bass , but only played at school and did assemblies with a couple of strummers, and didn't really try covering others numbers,
after not having picked up the guitar for a while , I heard 'silly love songs' by wings / McCartney and thought I could have a go at that , picked up the guitar and joined a band 3 weeks later , different band now but I remember nailing the line and getting a real buzz from it , even though it isn't to hard ,but it has a great grooove
