The weather was not kind, and while regular concert goers may be used to this sort of thing, the 15,000 who bought tickets for this were a different sort of crowd.
The concert was organized by Diana's brother, Earl Spencer, who is now lord of the manor. Spencer appeared with members of his family during one of the dry spells. Spencer's plans for the concert, the proceeds to go to Diana's charities, were not universally popular here.
The little neighbouring village of Great Brington feared being overrun and barriers were erected to keep the invading hoards out of town. They have similar fears about the crowds who will throng over the summer to see the Diana Memorial Museum that the Earl will open this week.
"I don't think he (Lord Spencer) could have forseen when it was decided to bury Princess Diana at Great Brington the enormous interest and emotion that would be aroused," Dr. Stephen Mattingly, a local resident told CBS News Correspondent Mark Phillips.
The traffic jam was still several-miles-long as the concert started on Saturday evening.
The concert is controversial enough in itself, but it only marks the beginning of the Diana commemorative season. That will run from now to the anniversary of her death at the end of August. And all along, the question being grappled with is not only how to best remember her, but also when is enough, enough.
Many of the big names of British pop - Elton John, Phil Collins - declined to perform at this concert. But the crowd seemed happy enough with those who did come; Chris de Burgh, old favorite Cliff Richard.
The Spencer estate where Diana is buried was bound to become a focus for the reverence in which she is still held. On Saturday, with musical accompaniment, the invasion of her fans began.
