Bob Dylan (right) and Van Morrison, two genuine legends of rock, kick off a short national tour today. As they're so moody and unpredictable, this pair can often disappoint, but when they rise to the occasion, it can be one of those all-time great nights. Well worth a risk, if only to say that you've seen them.

There are more old people on show at the all-day Ozzfest, and for many devotees, this will be the first chance to see the classic Black Sabbath line-up of Ozzy Osbourne, Tony Iommi, Bill Ward and Geezer Butler since 1979. But it won't be a gathering of balding beer-guts as retro metal is back in, and an undercard of the Foo Fighters and Pantera should ensure that the average age of the crowd will be half that of the headliners.
