Input: Question: How old was Bill Anderson the year that he helped co-write a song that became Wills's first No. 1 country hit? Passage:Wish You Were Here was Wills's second album. This was his most commercially successful, earning a platinum certification from the Recording Industry Association of America. The lead-off single "I Do (Cherish You)" and its followup, "Don't Laugh at Me", both reached No. 2 on the country charts, with the former bringing him to the Billboard Hot 100 for the first time. Following the pair of No. 2-peaking songs was the album's title track. Co-written by Bill Anderson, Skip Ewing, and Debbie Moore, it became Wills's first No. 1 country hit in 1999. Later that year, the boy band 98 Degrees covered "I Do (Cherish You)" on their album 98 Degrees and Rising. Following "Wish You Were Here" was "She's in Love", the final single from Wish You Were Here, which peaked at No. 7. In 1998, Wills received an Academy of Country Music award for Top New Male Vocalist.
