Henri Urponpoika "Trollhorn" Sorvali is a music teacher at the Sibelius-lukio (Sibelius High School) in Helsinki.
Moonsorrow's lyrics draw inspiration from Finnish mythology, legends and poetry; since Tämä Ikuinen Talvi they have been written exclusively in Finnish. For instance, the song "Sankaritarina" from Voimasta Ja Kunniasta features lyrics directly translated from Hávamál (Sayings Of The High One) , a single poem in the Poetic Edda, a collection of Old Norse poems from the Viking age.
Bassist Ville Sorvali and guitarist and main composer Henri Sorvali are cousins. Henri also plays keyboards in Finntroll.
While recording "Verisäkeet" Moonsorrow announced that the next CD would be more brutal, less epic and the songs would be shorter.
The CD was told to be titled "Raah Raah Blääh" and to contain 21 songs.

It was obviously a joke that the album would be Moonsorrow's next album and the real album "Verisäkeet" is nothing like that, but they did actually keep their word and record a full album of hardcore punk/grind songs as a side project called "Lakupaavi" (Liquorice Pope). The album is in fact called "Raah Raah Blääh" and does contain 21 songs + bonus tracks. It can be downloaded from http://www.lakupaavi.tk/. The opening song "Kuolema Taidehomoille...Ja Muille!" was available for download on Moonsorrow's site under Moonsorrow's name to further increase the confusion.

At least in some versions of "Verisäkeet" can be found a piece of paper where it reads: "Raah Raah Blääh" and "Kuolema Taidehomoille...Ja Muille" which are titles by Lakupaavi.
