Hej! I posted a reply with a link to a Youtube video where you can hear the name pronounced, but Youtube links are not allowed here, so it was deleted 🙁 But if you go to Youtube and search for "MIDNATTSTANGO, LASSE LÖNNDAHL, BINGOLOTTO 1996" you will find the clip and hear how "Lasse Lönndahl" is pronounced.
Ha en fin dag!
