Bulstrode here.

Did anybody hear this jazz programme and about 5:30 pm?

Because when the second act came on (the Charlie Mingus group) Julian
Joseph said something to the effect of 'the Spiderman movies having
stolen one of the band's compositions and now they're stealiong it
back'.

What was all that about? tongue in cheek or is there something of
sbstance here?

I'm a wannabe songwriter and I take a great interest in any matters
relating to copyright infringement.

BTW, the first act (tango-based) comprised a couple of superb
musicians. Magnifico.
