and there was this one 
which I was particularly proud of 
where I thought I’d caught 
just the right pace, then 
the change of pace when 
the poem goes deeper 
and then the perfectly chosen metaphor 
with a rallentando 
which made it musical 
and ended it just 
knock-’em-flat 
sheer poetry 
 
then last night 
I read your poems 
for the first time in oh fifty years 
and there it was 
almost identical and 
I realised where I’d got it from 
and the part of me that 
wasn’t bruised ego wept inwardly without naming any cause 
 
and maybe when I’ve recovered 
and demoted my poem in  
the collected works of pride 
I’ll marvel at the power of poetry even if yours not mine 
which can lie low in the mind 
for fifty years and not only that 
but may well, and here we should be careful 
but reflective, respectful even awed,  
have subtly infinitesimally but significantly 
like some homeopathic almost unquantifiable  tincture,  
altered my whole life. For fifty years. 
 
now that’s something
