The ’90s are everywhere in Las Vegas right now, and while R&B quartet All-4-One makes its home in the I Love the ’90s show on the Strip, the group’s country-music counterpart, John Michael Montgomery, is hitting downtown as part of National Finals Rodeo entertainment. In the mid-’90s, when All-4-One made the R&B and pop charts with singles “I Swear” and “I Can Love You Like That,” Montgomery topped the country charts with his versions of those same songs. He also had plenty of other country hits in the ’90s, including “I Love the Way You Love Me,” “Be My Baby Tonight,” “If You’ve Got Love” and “Sold (The Grundy County Auction Incident),” all of which hit No. 1 on Billboard’s country charts.

Although he hasn’t released an album since 2008’s Time Flies (featuring hit single “Forever”), Montgomery remains a popular draw on the touring circuit, bringing his baritone voice and straightforward country songwriting to audiences who still remember (and still love) the ’90s. “I’m enjoying my life getting to go up and down the road singing the hits I was fortunate to have,” he told Sounds Like Nashville last year, “and the fans still seem to enjoy them.”
