Well, as I posted elsewhere, my son (age 14) got chance to play at the Cavern Club (ie, birthplace of the Beatles)!
So, I just had to get some photos.
Not many are usable beyond the family album and I won't put any of the kids up on here before speaking to the other parents, but here are some of one of the semi-professional bands who also played that night. They are called the Mono LPs and are a local band.

They are all a bit noisy as ISO was up at 1600 (max). All shot in manual.

Thanks for all of the advice.
Yes, this was really difficult!
I ended up using the kit quite a bit to get the view I needed, but, yes; the manual lens gives a far better image. Having said that, focusing was a nightmare.

At the end of the day, my lad was on stage in an iconic venue, anything else is icing on the cake.
I'll upload some images over the next few days. None are spectacular, but some are worthy of comment.

Thanks.
I have decided to shoot in RAW ( I know, I know: I should always do that!)
I hadn't thought of under exposing and then "Over developing".
I have access to the sound check, so will use that time to practice.

HI Brad.
I'm in the same boat as others. Started with ME Super, then moved on to DSLR.
As has been said, the beauty with Pentax is that you can use your old lenses. (Or buy older lenses at a great price!)

Got an opportunity to photograph bands in the Cavern Club in Liverpool tomorrow.
It is a school event and my son is in one of the bands! (age 14).
I was planning to photograph him anyway, let's face it, this might be his only chance to play in a venue like this.
However, he has only gone and promised the school that, as I will have my cameras there, I can take lots of photos for them to use! Gulp!!

I'm using two K10d cameras.
I'm taking 4 lenses but plan on using just two.
Pentax K 50mm f1.7 : I'm hoping that this will be my main lens as it is a nice fast lens.
And then, either 18-55 kit lens, or my Tamron 70-300 (but I'm hoping to be allowed close enough to not need that) or my 28 - 80mm.

I will probably set ISO to 1600 and leave whichever lens wide open.

This is because it was private land. If the rugby match was on a local public park then no-one could stop you (legally).

Thanks David, that means a lot, coming from you.

Bill: Yes, it was dusk. The ones I took earlier in the afternoon came to nothing. The light was too flat. I deliberately waited around until dusk to see what I could get.

Thanks guys.
I would have liked more time with the young lads there, but "security" moved them on.
I took quite a few shots of the poppies, but that was the only one I was really happy with.

Try again.

Yeah. Strange, they've gone from my Photobucket account, too.
I'm just about to upload them again.
