Hello all and Happy New Year

I've been monitoring this site for some time, and I know that this is the right place to get an answer for my question.

I'll be travelling out of SIN on SAS in Business. As far as I know, SAS departs from Terminal 1.

However, if I went to the Singapore Silver Kris Lounge at Terminal 2, will they let me in, as I'm travelling on a Star Alliance Business Class?
