need some help learning "always look on the bright side of life" cg 40 button anglo

[accordian]

hello.

 

i'm not going to lie I never learnt how to play my anglo because I could never figure out what was possible, get half way through multiple songs realised I needed

notes on both the push and pull and gave up. I think this song should be possible but I cannot figure it out. getting really frustrated as I cant seem to play hardly any songs on it.

garry coover type tabs would be really handy thanks
