After almost a decade of full-time bass encompassing the British and U.S. Military, Universities, Clubs and so on during my late teens & twenties, I took up my secondary Art form as an acrobatic, architectural, masonry painter & decorator for a while during the times when I was songwriting and studying guitar and Lute.
Now I am old - I can do just music and songwriting but I am a Sports Official (Cricket) and Press reporter (Soccer) to keep up the interest although, when I told F.C. Club Prez that nobody has asked me to play footie for a couple of decades, he mentioned that age may be the reason, therefore, the County F.A.(Amateur levels) would probably refuse Insurance coverage. With 10 guitars/basses 2 keyboards 5 recording devices and a 30 year old Quadrophonic Vinyl record deck rigged up to my Bass rig - who needs a boring non-music job when the Pension takes care of all else. Most of you - don't give up your day job. I have roamed and never bought Real Estate. Any bassists who can get round the career idea: It will be a struggle now and then so track round Studios, run with 3 or 4 bands and only decline the most dire of offers. The best Live work is in clubs and cabaret so aim for that circuit. You can always fit in other occasional bands gigs. The competition is fierce but there is far more work in U.S.A. than in U.K. U.K. bassists must be prepared to spend months at a time in Europe etc.
Did all that 40 years ago - so I know the score.
