On the Collector Record website we found this CD titled '55 #1 hits'. CD 1 contains the same tracks as the standard #1 hits CD, the second disc contains mostly standards like 'Loving You', 'That's Someone You Never Forget', 'Spanish Eyes' and 'You Don't Know Me'.
We have no information if this 2CD-set is a bootleg or not, on the back we read 'Universal' as the record company and (c) 2002.
