Hair band Nelson was massive in Australia in 1991. Here's an interview with them from Australian TV at the time. NELSON is an American hard rock band founded by singer/songwriters Matthew and Gunnar Nelson (the twin sons of Ricky Nelson and Kristin Nelson). NELSON featuring the twin lead front men had a No. 1 hit with "(Can't Live Without Your) Love and Affection" in 1990/1991. They are listed in the Guinness Book of World Records as the only family to reach number one record status in three successive generations (beginning with grandparents Ozzie and Harriet Nelson). In 2010, Mark Slaughter joined NELSON on tour as lead guitarist. They recorded the song "Two Heads are Better Than One" under the name Power Tool for the film Bill & Ted's Excellent Adventure. (Dweezil Zappa assisted with this production.).
