I still have the cassettes of that Hasc concert. Its Hasc 4 and it still makes for some gr8 listening (its one of my parents favorite concerts). Its a triple cassette with the 2nd cassette entirely for the London School of Jewish Song besides the last 5 mins. Its available at music sites like mostly music and I only recently bought the dvds of Hasc 4 for my parents from there.
They sing the entire ki yikorei song and also most their other gr8 hits like ko amar, ashira lahashem bachayay, vchi yadav shel moshe, hamalach, hamavdill and all the others too.
