I did this but the other way round - I was in the US and wanted to stream some UK only content.
Grabbed myself a cheap UK VPS and then tunneled through it using SSH so it looked like I was in the UK.
All you would have to do is use a cheap VPS say in the US (although I recommend Germany, bit more expensive than the US but latency / ping times etc near enough the same as UK) and tunnel through that.
If you don't want to SSH tunnel, try looking at antinat on a Linux VPS and limit it to your IP only, same effect and there are step by step guides for that one.
Tor would work if you can guarantee that you don't hit a high load / slow bandwidth node, never really used it myself to a great extent but to me it always felt slower than a slug going uphill in a headwind - maybe I was unlucky!
Hope that helps,
