It's been a while since Dan Seals had to sleep under a piano in the recording studio because he couldn't afford to rent a room.

In a career that looks like a roller coaster ride - with the highs so high, and the lows so low - Seals seems to have achieved a level at the very top of the country music charts. One of the hottest tickets in country music, he's wracked up an impressive list of No. 1 hits since he began his solo career nine years ago.Friday, he'll present two concerts at Lagoon. The concerts, at 6 and 8 p.m., are free with admission to the amusement park.

Country fans know his sound. But pop music lovers who may not think they know Dan Seals have been enjoying his music for years, first as a member of Southwest F.O.B. and later as "England Dan" of England Dan and John Ford Coley.

The Iraan, Texas, native began his career as a child, standing on an apple crate to play a stand-up bass, while brother Jim (of Seals and Croft fame) played the fiddle in the family band.

From there, he played with garage bands, then enjoyed mild success with Southwest F.O.B. When they split up, he and fellow bandmember Coley formed their popular mid-70s acoustic duo. Dissolution of the act a few years later left Seals mired in financial and legal difficulties - he even "suffered the ignity" of watching the IRS haul away his Volkswagen van."

After four years of scraping along without getting anywhere as a solo artist, Seals hit with "Everybody's Dream Girl," and has since followed it with a score of hits, including "You Still Move Me," "I Will Be There," "Bop" and "Meet Me in Montana" (recorded with Marie Osmond).
