Johnny Theakston and the Tremeloes

Today's House Points from Liberal Democrat News. My current Alvin Stardust fixation and Tuesday's extreme heat produced something distinctly odd.

But it was meant to be. Delayed for ages at Leicester station on Tuesday evening, I sat in the buffet and made some notes for this piece. They were playing hits from the sixties and seventies and, sure enough, "My Coo Ca Choo" came on.

Identity crisis

Identity can be a complicated business. Take the case of young Bernard Jewry, who developed a love of rock music and hung out with a band called Johnny Theakston and the Tremeloes. In 1959 the band sent a tape to the BBC under the name Shane Fenton and the Beat Boys. Then tragedy struck: Johnny died.

When the BBC wrote back asking Shane Fenton and his band to play on a live radio programme Bernard Jewry became the new Shane Fenton - he even changed his name by deed poll - and a pop career was launched.

But musical fashions change, and after four hits Shane Fenton faded from view. Until in 1973 he was reborn as Alvin Stardust with the single "My Coo Ca Choo".

There are two reasons why the career of Bernard Jewry/Shane Fenton/Alvin Stardust is topical.

The first is that makes you wonder how the government's identity card scheme would cope with him. According to Joan Ryan at home office questions on Monday, everything is in on course. Cards will be phased in from 2008. "I repeat: 2008," she added, on the basis that if you say something often enough it must be true.

If you prefer to believe the officials working on the scheme, then the current plans are not remotely feasible. According to leaked e-mails, they fear a botched introduction that could delay ID cards for a generation.

Of course, for Liberal Democrats that would be very good news. But we must be wary of relying solely upon government incompetence to see ID cards off. We must continue to argue about the principle, showing people how these cards threaten a fundamental alteration in the relations between citizens and the state.

The second reason for being interested in Alvin Stardust is that his manager was a streetwise young accountant called Michael Levy. Today he is better known as Lord Levy.

What would people in 1973 have made of the idea that one day Alvin Stardust's manager would be arrested and there would be excited talk of the prime minister resigning?

Lord Levy once said that he and the prime minister were "like brothers". I doubt he would say that now. Tony Blair will have to find someone else to be his coo ca choo.
