Stateside fans hoping to catch rising Scottish reggae-rock singer Finley Quaye in the act will have to wait a bit longer.

Quaye abruptly canceled four U.S. tour dates and flew back to the U.K. over the weekend after his guitarist quit the band.

The singer, who has received wide acclaim and platinum U.K. sales for his debut album "Maverick With A Strike," left the country in a huff when the guitarist left the group after Friday night's gig at New York City's Roseland Ballroom.

Quaye was scheduled to open for Ben Harper Saturday night in Philadelphia, then was to play two shows in Washington, D.C. and one more in Boston.

The last time we caught up with Quaye, two weeks ago, he seemed optimistic about the outing.

"I'll be looking forward to that," Quaye told MTV News of what was then his upcoming stint with Ben Harper. "There'll be some really good people at Ben's shows, you know, people who appreciate music. I find Ben... obviously, he's hurt sometimes. He uses a lot of slide guitar, lap steel blues guitar, and his music is often melancholic, and that's all a part of the emotional world, you know. But I'm not going there to support that or to back that up or to highlight that at all. I'm going there to play our music, which is a variety of music."

There's no word yet on whether Quaye will be able to make up any U.S. dates, or if he'll be able to play an upcoming series of sold-out London shows.
