Jimmy Buffett [ tickets ] continues to fill in the gaps on his upcoming "Year of Still Here" tour, an endeavor that looks to keep him busy through the end of summer.

The singer has added several new dates, most of them in June, to the trek, which at the moment looks set to kick off April 21 in Woodlands, TX. The full schedule is listed below.

Most of the shows are currently on sale, while Buffett's June 12 show in New York City and an Aug. 24 date in Atlantic City, NJ, will go on sale March 31.

Buffett continues to support his latest studio effort, 2006's country-leaning "Take the Weather With You," which became his second consecutive No. 1 debut on Billboard's Country Albums chart.

The performer also released a pair of live recordings last year: November's "Live in Anguilla," which captures two recent shows on the Caribbean island, and April's "Live at Texas Stadium," which revisits Buffett's 2004 Dallas concert with Alan Jackson and George Strait. The trio's cover of Hank Williams' "Hey Good Lookin'" from the latter set netted Buffett his second career Country Music Awards nomination in the Event of the Year category.

The leader of the Parrotheads continues to stay busy with several other endeavors, including a new restaurant under construction in Waikiki, HI; a foray into the casino business in Biloxi, MS; and a new book, "Swine Not?," which is due in May.
