Wakefield without Wiltschinsky

The duo had been booked to play in Wakefield but again Robin had to go it alone. It wasn't as stressful this time as he knew in advance and the organisers were happy to hear Robin's solo performance. They have seen the duo many times and realised they were still in for a great evening.
Robin always introduces the pieces with a little bit of information to make it interesting for the audience. Both Robin and Peter have composed and normally introduce each others compositions.
As Peter wasn't there Robin had to announce his own piece, 'Canzone', and this is what he said.
"Normally Peter introduces this one, I told him with a name like Wiltschinsky he shouldn't have gone to that sushi bar."
The audience were highly amused, and Robin has been asked back again, so I guess that was a good sign.
It sounds to me like he's trying to carve a little niche for himself as a stand up comic!
