I'd just like to point out that Lulu's was not a 60s comeback as she'd had a top 3 hit in 1974 almost four years to the day from her TOTP performance with Bowie's "Man Who Sold The World", IMO one of the best Bowie covers.
Agreed. Not that there's too many Bowie covers to choose from. Not hit singles anyway (Mott excepted).
It helped that it was basically a Bowie record but with Lulu singing. Featuring as it does, the dame producing and on sax, guitar and backing vocals, Mick Ronson on guitar, Trevor Bolder on bass and Mike Garson on piano.
