I've been singing with the Houston Symphony Chorus since the '88-'89 season, so I've done most of the big standards and a lot of the not-so-standards. See my list of works performed for more detail. I've also taken voice lessons for most of that time and done some solo work, including a bit of semi-pro for the Christian Scientists, and occasioinal paid choral work. Another pretty regular musical activity for a several years was a small group of singers (usually five of us -- some pictures here) that met at my house to do ensemble singing, which is essentially vocal chamber music (sort of like a string quintet except with singers). I've also attended Western Wind ensemble singing workshops for a number of years, a venue that I thoroughly recommend.
In high school I trained fairly seriously as a pianist, but I haven't played for decades. My piano skills have largely atrophied, but recently I've been playing a bit more.
