Herself (being much younger than me),has an extensive collection of "Best of the '60s" compilation tapes, at least one of which always seems to accompany us on long journeys. They all seem to contain either"I'm a Believer" or "Last Train to Clarksville" which are thus indelibly imprinted on my brain. But, of course, Lonnie Donegan and at least one blues tape and some jazz, are also there to counteract the effect!
