To Music or not to Music?

So, tomorrow night my girlfriend and some of her friends are going to watch GU Medicine, i've never heard them.

Seeing my girlfriend at the weekend is a carefully weighed process, do I see her Friday night or Saturday night? And involves some of these:

1) If I sleep for 12+ hours on Friday night, I feel great the rest of the weekend, Trying this on Saturday doesn't have the same effect. I can't sleep with Catherine that long, because, well, I don't know why, I just wake up earlier.
2) If I go out on the same night as Catherine, then it avoids the "What do you want to do?" question, since we're out. We've been going out for nearly 5 years and still don't live together mostly due to money (we like spending it too much, rather than not having it).
3) If she's going out on Saturday, Win win for points 1 and 2, otherwise, what to do...
4) Where is she going out? To see a band i've never heard of rates low.
5) Is she wearing something specific? She looks great, if she's going out, I can be swayed to come out as well if she's wearing something really nice.

They're just some examples.

A weekend or two ago she was going out and I didn't want to come, but she was wearing something specific and it swayed me. We watched a band i'm not particularly bothered about, in a pub I hate (and this was only the second time i've been in it). After the band finished, we stayed in the pub until 4am or something.

I personally like Metal, some stuff that you might call Dance, and some Classic Rock. Indie music has always bored, annoyed, whatever me, and I really can't do with it, whether it's something like Oasis, or something more moden like Kaiser Chiefs. And it's Indie that this pub played.

I had a crap night, listening to crap music, in a pub where the prices were high for bad drinks.

So, this weekend, Friday night, Catherine is going to see a band in this same crap pub, do I want to go? Looking at the evidance, no. But, this time Tom is going, and he said if the music was bad we could go somewhere else, will he follow that up? He can be a let down in situations like that, due to changing his mind and wanting to stay with "The Girls", Catherine and her attractive stick thin single best friend, who Tom swears he's over and couldn't care less about.

But having a Sunday free would be nice, not sure what for though. And we could do with going to the Travel Agent on Saturday. And I'm unsure if another Saturday night watching crappy TV will be overly exciting, although it's nice to spend the time with Catherine. Unfortunatly, the question "What do you want to do?" leads to me responding "Play on the Computer?"...
