     When Bill's family moved to the Chicago area in 1963, an old guitar was found above a wood pile in the garage of the home they bought. The old Kingston six string wasn't in very good shape, but it was Bill's entry way into the music world. After a discouraging series of music lessons (10 for $10) mentioned in the song Stubby Finger Blues, Bill decided to teach himself the guitar and started singing at coffee house in the area, including the No Exit in Chicago. Despite less than encouraging reviews by classmates, Bill kept writing and singing wherever and whenever he could.
     Lin learned to play piano at an early age and guitar in high school.  She and her friend, Jolynn Wall, formed a folk singing duet in the mid-60's and performed in the Milwaukee area. Their rendition of Seven Nights Drunk was a fan favorite, though not well received by some of the faculty at their high school, Pius X.
     Theiss & O'Connor is currently taking a break from performing as a trio.  Over the years they have been accompanied on stage by Tom McGirr (bass), Brandon Herbst (bodhran), Lori Otto (flute), and to name a few.  Since the late '90's Chris O'Connor has joined them on bass and Tim O'Connor on guitar, bass, and mandolin. And the group welcomed the percussionist from 'Tis, Tom Mortenson, at Irish Fest 2012 and on their latest recording.
     The group originally formed in 1967 when Larry and Bill met at an "open sing" at The Coffee House in Milwaukee.  They each played in separate groups (The WPT Cable Company and the New East Town Singers) for a time, but finally decided that, with Lin, they could create the sound they were after. They have played at colleges, coffee houses, night clubs, and festivals in the Midwest, some of them listed on the left. 
     After a twelve year hiatus to raise a family and to explore other musical ventures, they reunited in 1996. They have since performed at various venues throughout southeastern Wisconsin and northern Illinois.  They have performed on television several times and have had songs from their CDs played on local, state, and international radio programs.  They have recorded four CDs as a group and a half dozen more in other efforts.  Larry has three classical guitar Christmas recordings as well as two recordings of religious music.  Bill and Lin collaborated with Mary Ellen Backes on a Christmas CD and Bill has released an album of some of his original songs. Larry has published several of his songs in two song books and Bill's An Irish Blessing has also been published, sung by various choirs, and recorded in a joint effort by the Irish Fest Choir and the Omagh Community Choir (2001).  Their three-part vocal harmonies are accompanied by accomplished guitar work.  Their sound is tight, powerful, polished and refreshing.  They  perform a mix of original, traditional, and Irish-American folk tunes, but have also been known to throw in occasional unexpected songs of  different genres. They continue to put their unique talents into all their musical efforts. After Irish Fest, 2014, the trio is taking a break and working on separate music projects.
     Bill & Lin continue to perform Irish songs, original songs, folk songs...well really any song that fits their style and that they enjoy singing. And, of course, Bill has stories to tell.

"One of Milwaukee's finest. Their repertoire seems designed to be an entire evening's entertainment... They've also got a lot of class."

     - Cindy Frisque

"Larry and Bill provide wonderful acoustic guitar counterpoint that provides a musical landscape for songbird Lin O'Connor and the ensemble's liquid, wistful harmonies."
       - Michael Kunan, Music Dept. Manager, Borders Books and Music, Fox Point, WI
