I spoke to Lori at Record Rama (daughter of owner Paul) She has a 45 of Dreams but it is an "Archive Copy" That means that they always keep at least one recording of everything. Lori said the song "Dreams" is on the "I Really Want You" album. She has a copy of the LP but it's an archive copy too. The song length on the 45 is 3.46.
She'll make a copy to CD for $25.00 and it will take 2 weeks or if you want it fast, she'll make a copy to cassette for $12.00
I asked her if the LP song was longer than the 45, she said she didn't know. Ususally, the LP version is always longer than the radio version. I didn't ask what she would charge to make a copy of the entire LP but if the charge is the same, maybe consider getting a copy of album.
