Dame Vera Lynn is on course to make the top 20 at the age of 97 - extending her lead as the oldest living artist to figure so high up in the album chart.
The Forces' Sweetheart released Vera Lynn: National Treasure - The Ultimate Collection this week and if early strong sales continue throughout the week she could even make the top 10.
Her last major chart feat was five years ago when she achieved a number one with an earlier best-of release.
Dame Vera's latest album comes as preparations are taking place to mark the 70th anniversary of the D-Day landings on June 6.
She will also have a role in a major commemorative concert at the Royal Albert Hall on the evening of the anniversary when Katherine Jenkins duets with a recording of her singing the popular wartime hit We'll Meet Again.
The track featuring both their voices also features on the new album, along with a number of previously unreleased recordings of Dame Vera - who made her professional debut at the age of seven - which were unearthed by her daughter Virginia.
In an interview published last week she expressed surprise that her wartime role, buoying the nation's spirit through song, was still so strongly recognised.
She said: "I never thought the Forces' Sweetheart tag would stay with me, but it has, hasn't it? I thought it would last for the war period, then I'd just be another singer. Of course I've never minded that everybody always connects me with that time. It was so important."
The Official Charts Company will announce the midweek placings tomorrow (June 4), with the actual chart issued on Sunday June 8.
