I have found acompilation entitled "Brum Beat Live At The Barrel Organ" from 1980. It features 13 bands, thus is not acceptable by the MA rules.

However, it exist in two versions. It was also released as two separate LPs, one featuring six bands and one featuring seven bands. Even though it doesn't feature any acceptable bands (the closest candidate Speed Limit has released a Melodic Hard Rock LP two years before), I am wondering what is the site policy in such cases, since I don't think this is an isolated case?

In that case, the standalone release Brum Beat Live at the Barrel Organ! - Volume 1 could be added to the database, but not Volume 2 or the entire product.

Sorry, I thought I have replied to you before.

Anyway, than you very much for the answer, I'll have it in mind if I stumble upon similar compilatons/splits.
