What if songwriter extraordinaire Yasushi Akimoto（秋元康）hadn't help create girls' groups such as Onyanko Club（おニャン子クラブ）in the 1980s and AKB48 in the 21st century but instead made a boys' group a la the teams in the Johnny's Entertainment world?
Well, wonder no longer. I'm not sure whether Akimoto actually did create the group Musukko Club（息っ子クラブ）but on its Wikipedia page, it's been described as "...a short-lived male spin-off idol group of Onyanko Club". So, instead of cute girl-next-door types conglomerating, it was a group of 7 strapping young men that was officially formed in early 1986 with their first of two singles coming out later in September.
"Boku-tachi no Season" (Our Season) is this strange mix of Art of Noise sound effect and a 50s-ish rockabilly melody a la Checkers. As it is, it doesn't sound too bad for an 80s aidoru tune and the guys certainly don't slum through the song. Akimoto was indeed in charge of lyrics with Masakazu Togo（東郷昌和）taking care of the music.
I don't know how "Boku-tachi no Season" did on the charts but the season for Musukko Club didn't even last a year. The Johnny's groups such as Hikaru Kenji（光GENJI）were at the top of the heap and a good chunk of the television viewers at the time were male fans looking for girl aidoru and aidoru groups so things were probably tough for Musukko Club from the get-go and they never got that popularity. So the breakup was official at their last concert at the Budokan in February 1987.
Some interesting trivia that I picked up on the J-Wiki page for Musukko Club was that apparently future actor Yuji Oda（織田裕二）and future Unicorn vocalist and producer Tamio Okuda（奥田民生）had actually auditioned for the group with the former passing but deciding to drop out at the last minute.
