Here is my recipe for a 60/-. I'm pretty sure it originally came from an old episode of Jamil's show. The first time I made it I served it my neighbor from near Belfast without telling him what kind of beer it was. He said it was really nice, and "reminded him of the beers he had when in Scotland every year after finals". I've made it a few times since, varying the MO depending on how strong I wanted the beer to be and leaving the specialty malts unchanged (I think JZ recommended that too).
For 10 gallons:
9 lbs Maris otter
2 lbs crystal 40
1 lb honey malt
1/2 lb crystal 120
6 oz chocolate malt
60 grams fuggles 4% AA @ 60 min
Yes, it has a bunch of crystal in it. But when a guy who has a had a lot of beers in Scotland tells you, unprompted, that it reminds him of those, I think you've hit the mark.
<edit> sorry, mash at 158F for 60 minutes
