Thanks so much to Jadan_Smith , Fluke_Skywalker , Doc110894 , and jokerswild1 for your replies here .
I'm so glad you enjoyed this song as much as I - great 1980's family fun song .
Thought maybe it was the 80's soundtrack king; Kenny Loggins
You're most welcome Jadan_Smith and I totally agree he does sound a bit like singer Kenny Loggins with a bit like the lead singer El DeBarge from the family band " DeBarge " ( IMPO anyway ) .
It's actually Michael Sembello and here is his Wikipedia profile page : ( it appears he has done more songs for other 1980's movies as well ! )
