Thanks for the list. I'd forgotten how much of a slow burner 'Saltwater' was getting to the top, and wasn't aware it took 11 weeks just to get into the Top 50. 'Tingles (EP)' really collapsed around the time their 'Blind Love' album was released. Maybe this was one of the early instances of discontinued release policy? This is probably a list where songs from this century will find it difficult to place well in.
Although not consecutive weeks in the top 100, Merrill Bainbridge's 'Mouth' was first released on 24th October 1994, and didn't hit #1 until the chart dated week ending 21st May 1995. That's 29 weeks to reach #1, counting from the first week it would have been eligible to enter the chart (week ending 6th November 1994).
Young MC's 'Bust a Move' was first released here in 1989 (some time between August-October 1989, I'm pretty sure), and didn't reach #1 until late October 1990, after a re-release. Last edited:
