Procedure; Airspace Structure
[I] was working Nashville Approach on an IFR flight plan that routed us to the east of Nashville; on a northwest track. Approach gives us an 80 degree heading change for vectors around a military operating area. We found that strange; as there were no NOTAMs; TFRs or MOAs depicting this activity. When asked what the deal was; Approach said that was a jet practice session for an up and coming air show. We strongly feel that if a group of military jets are practicing for an air show; at LEAST a NOTAM would be appropriate. We would have normally flown this route VFR and would have never known.
A BE58 pilot filed IFR on a route he normally flew VFR and on this particular day was vectored around a non NOTAMed military airshow training session which he would not have known about if VFR.
