Damn, just finished listening to this show. What a cool show - cheers to the Can You Brew It? crew for taking on such a daunting challenge. Mraz is the perfect guy to bring in on this one.
Gotta love a low alcohol beer like Bam Biere with big complexity.
Substitute for Crystal? Tough one, since that's such a signature hop of the beer.. But...
Since crystal is a Hallertau/Cascade cross, you could try a blend of those two directly, or if you can't get your hands on that, do something like Mt. Hood/Amarillo. Sterling with it's noble spiciness & citrus qualities would be another interesting choice for a beer like this.
