Thank you for coming back to me, it's being performed at "The Greenwood Theatre" near London Bridge, it's quite a large space with relatively low-level lighting - there will be some LED's in use, we will be able to get up close to the performers as well as longer shots if we wanted as the photos are taken during a final dress run.
I hope that is enough information but if you require any further information please do let me know
Relatively low level, will it be consistently low level, or significantly brighter in some spots than in others? If you have a lighting designer, they'll be able to tell you this - if the lighting is being done by the theatre technicians, then it would likely be more consistent, albeit yes - low level, which is usual ...
In any case, you will need a higher ISO (but of course, as low as you can get away with, but it wouldn't be very low) and a high shutter speed. I shoot theatre and dance in Manual mode to manage the exposure as best possible - if your dad can get a test shot before the rehearsal begins, he can get the settings he'll need (more or less) to shoot from there, and keep to those unless the light changes dramatically. I would recommend shooting in RAW - this will help if the exposure does change and there isn't time to react, and if the lights are LED then they may use a lot of coloured light, and you can deal with this much better in RAW than with a JPEG ...
I've found a picture of the theatre via Google ... here.
The stage level with regards to where you'd be shooting means that if you were to higher one lens I think you could get away with a 17-55 (f/2.8 IS). You wouldn't get very many single dancer tight crop photographs, but for documenting the show it would be alright and give you the possibility of wider shots and stuff a little bit closer ...
The 50mm 1.2 lets in a lot of light, but the autofocus is intended for portraits in good light, not dance in low light, so something else would be required. If you can stretch to two rented lenses, I think a 17-55 f/2.8 IS and an 85mm f/1.8 would be good on the 60D - the 85mm will be effectively about 120mm (I've lost the knack for doing this calculations in my head now I use full frame) and the 17-55 wide enough for whole stage shots and long enough for something a bit closer, if your dad were able to stand (not sit) at the front during the dress rehearsal, he wouldn't really be in anyone's way and you want a bit of height to avoid photographing everything from below ...
I'm not going to tell you to hire someone, because you've said that you can't ... hopefully this helps you to make the best of the situation you have.
