You could argue the PGP key that signed isn't yours. PGP is entirely
relative, so unless you had established it was your key is some very strong
non-WoTty way (like by getting up on stage and saying "this is my key
fingerprint" or handing out business cards with it on), then you could
still end up with some deniability.

It's for this reason that in Europe, digital signatures are only considered
valid if they're made with a PKI certificate.
